COHERENT CONFIRMS RECEIPT OF UNSOLICITED PROPOSAL FROM MKS INSTRUMENTS

Announces Intention to Enter into Discussions with MKS

SANTA CLARA, CA, February 8, 2021 – Coherent, Inc. (NASDAQ: COHR) (“Coherent”) today announced that it has received an unsolicited acquisition proposal from MKS Instruments, Inc. (NASDAQ: MKSI) (“MKS”) to acquire Coherent in a cash and stock transaction. Under the terms of MKS’ proposal, each share of Coherent common stock would be exchanged for $115.00 in cash and 0.7473 of a share of MKS common stock at the completion of the transaction, subject to customary closing conditions including receipt of U.S. and foreign antitrust approvals and stockholder approvals. ​

On January 19, 2021, Coherent announced that it had entered into a merger agreement with Lumentum Holdings Inc. (NASDAQ: LITE) (“Lumentum”) pursuant to which Lumentum agreed to acquire Coherent and each share of Coherent common stock would be exchanged for $100.00 in cash and 1.1851 shares of Lumentum common stock at the completion of the transaction, subject to customary closing conditions including receipt of U.S. and foreign antitrust approvals and stockholder approvals.

Coherent’s board of directors is evaluating MKS’ proposal and has not made a determination as to whether it is superior to the Lumentum transaction under the terms of Coherent’s merger agreement with Lumentum. After consulting with its financial and legal advisors, however, Coherent’s board of directors has determined that MKS’ proposal could lead to a transaction that is superior to its pending transaction with Lumentum and, accordingly, Coherent has determined to engage in discussions with MKS to further evaluate the comparative benefits and risks of MKS’ proposed transaction relative to Coherent’s pending transaction with Lumentum, including the near and long term financial opportunities of each transaction, the expected completion timing of each transaction, and the closing risks associated with each transaction. There can be no assurances that Coherent will conclude that the transaction proposed by MKS is superior to Coherent’s pending transaction with Lumentum and Coherent investors are encouraged to await a final determination from Coherent’s board of directors.

Notwithstanding its receipt of MKS’ proposal and pending discussions between Coherent and MKS, Coherent’s board of directors continues to recommend Coherent’s merger agreement with Lumentum to its stockholders. Coherent’s board of directors is not modifying or withdrawing its recommendation with respect to the Lumentum merger agreement and the Lumentum merger at this time, or proposing to do so, and is not making any recommendation with respect to MKS’ proposal at this time.

Bank of America is serving as financial advisor to Coherent and Skadden, Arps, Slate, Meagher & Flom LLP is serving as legal advisor.

Coherent Debuts Another Major Leap in Fiber Laser Welding Technology

Santa Clara, CA, June 4, 2020 – The new Coherent HighLight FL4000CSM-ARM fiber laser builds on the success of Coherent HighLight ARM fiber laser series already qualified for automotive applications. This new laser enables more advanced welding capabilities for high thermal conductivity metals, and aligns to welding requirements for e-mobility, energy storage, and general electrical interconnects consisting of dissimilar materials, such as copper and aluminum, and foil stacks that require precise control.

This new technology represents a significant improvement in simplicity, and overcomes the limitations of other joining technologies. The latter include unstable welds due to welding head wear and the large heat affected zone caused by ultrasonic or standard fiber laser welding. The ability to move beyond the limitations of traditional fiber laser for welding thin conductive materials is possible because of its unique dual beam output (center beam surrounded by a ring beam). The center beam has extremely high brightness (nominal BPP 0.6) allowing a smaller spot size compared to its multi-mode counterpart. The small spot size results in very high laser intensity that minimizes heating of the material, and, together with the pre-heating effect achieved by the ring beam, significantly improves stability of the melt pool and therefore weld consistency that is a challenge when welding thin conductive materials.

The Coherent HighLight FL4000CSM-ARM has been developed at the recently expanded “Center of Excellence for Fiber Lasers” in Tampere, Finland and is available with an output power of 4 kW (1.5 kW center beam, 2.5 kW ring beam). As with other Coherent Adjustable Ring Mode lasers, power in the center and ring beams can be independently varied and modulated. The CSM-ARM is supplied with a 15 m length process fiber, making it easy to integrate in virtually any production environment, and is compatible with the standard process heads from Coherent and other manufacturers.

Diode Laser Offers High Output Power in a Compact, All-in-One Package

Santa Clara, CA., April 16, 2020 – The Coherent HighLight™ DL HPS is an industrial diode laser that offers high power output (1 kW to 4 kW) in a compact, self-contained package, making it particularly useful for systems integrators and end users performing metal cladding, heat treating, brazing, and welding. The HighLight DL HPS utilizes an “all-in–one” configuration, meaning that the laser head, power supply, water chiller, and heat exchanger are all contained in a single enclosure. Yet, this enclosure measures only 670 x 1050 x 1760 mm, making it suitable for space-constrained applications, such as those often found in the automotive industry.

Another significant advantage of the HighLight DL HPS is that its conduction-cooled laser diodes enable the closed-loop chiller to utilize distilled water. This allows for a much easier implementation when compared with products which require the complexity and expense of deionized water.

The HighLight DL HPS is available with numerous factory options and accessories. The near-IR output is delivered through a detachable delivery fiber terminating in a choice of QBH or QD connector. Coherent also offers a wide variety of processing heads, including zoom focusing units, which enable the output to be tailored in size, shape, and intensity to the specific requirements of each application. This makes the HighLight DL HPS suitable for a wide range of applications in industries as diverse as oil/gas, agriculture, construction, 3D additive manufacturing, and semiconductor fabrication.

Coherent Creates Center of Excellence for Fiber Lasers in Tampere/Finland

Santa Clara, CA, April 2, 2020 – Coherent, Inc. has expanded its fiber laser operation in Tampere, Finland, and designated the facility as a “Center of Excellence for Fiber Lasers”. Fiber lasers themselves have been produced at this location since 2003. Now, in order to further streamline the production flow, Coherent will combine stand-alone fiber laser source assembly and testing at the same site with the manufacture of fiber laser components, laser engines, and combiners. This Center of Excellence for Fiber Lasers will become the source for all Coherent HighLight™ fiber lasers series, comprising industrial high-power fiber lasers with output powers ranging from 1,000 W to 10,000 W and a wide range of beam qualities – including single-mode, multi-mode, and adjustable ring mode – delivering superior results in a variety of challenging welding tasks. Coherent shall place particular focus on a new generation of lasers that offer additional benefits, such as full range of adjustable output powers (from 1 to 100% of rated power) and dual beam, ring mode, with truly independent center beam and ring beam power control.

This Center of Excellence for Fiber Lasers will bring together Coherent’s fiber laser manufacturing and testing expertise into more than 53,000 ft² (5,000 m²) of production floor space, including more than 10,000 ft² (1,000 m²) of cleanroom devoted to fabrication of critical optical components. The location will also house an applications lab featuring the full range of Coherent fiber lasers, industrial welding heads, and related state-of-the-art analysis tools for weld seams. This facility, together with Coherent’s existing global applications network, helps to ensure that customer requirements are rapidly translated into reliable process recipes and superior customer results, no matter such customer’s location.

“The fiber laser business is becoming increasingly competitive, so Coherent is pursuing this expansion to ensure that we deliver high-quality products while also reducing costs,” notes Jarno Kangastupa, the newly appointed Managing Director of the Tampere site. “Specifically, having the entire production process at one location is designed to reduce cycle times and give us better control over quality and reliability. For the customer, the intended benefit is the ability to get high performance, customized, and cost-effective fiber lasers on a shorter timeframe.”

New Thermopile Sensors Enable Laser Power Measurement up to 6 kW

Santa Clara, CA, March 17, 2020 – Coherent has extended the capabilities of its PowerMax series thermopile sensors to enable measurement of laser powers as high as 6 kW. The new PM1K+, PM3K+ and PM6K+ water-cooled, thermopile sensors incorporate the novel BB+ broadband coating to deliver reliable power measurements of CW or modulated lasers up to 1 kW, 3 kW, and 6 kW in output power respectively, within the spectral range of 190 nm to 11 µm.

The ability to sustain high power densities (≤14 kW/cm² at 1 kW, and ≤2.3 kW/cm² at 6 kW), together with a large, 50 mm diameter active area, makes these new PM series sensors particularly useful for measuring fiber lasers, CO₂ lasers, and other high power industrial laser sources. Additionally, each of the sensors is available with three possible connectors - DB25, USB and RS-232. The DB25 versions are compatible with several of the Coherent standalone power meters, including LabMax-TOP, LabMax -TO, LabMax-Pro SSIM, FieldMaxII-TOP, FieldMaxII-TO, FieldMaxII-P, and FieldMate, making them a suitable choice for both laboratory use and field service. The USB equipped models plug directly into a PC, which is most useful in manufacturing, QA and testing applications, particularly where data logging is required. Finally, the RS-232 versions are primarily targeted for embedded OEM integration, since these can plug directly into an industrial system controller. Then, the sensor can be controlled via direct host commands or through applications software included with the sensor.

Latest One-Box Femtosecond Amplifier Delivers Record Pulse Energy

Santa Clara, CA., February 10, 2020 – Coherent will introduce the Astrella HE at Photonics West 2020 (San Francisco, CA) – a one-box femtosecond amplifier that delivers up to 9 millijoules at a repetition rate of 1 kHz. This is the highest pulse energy commercially available from a water-cooled, single-stage, kHz regenerative amplifier. The use of closed-loop water cooling simplifies the installation of this titanium:sapphire amplifier and also lowers the capital and operating costs. The new Astrella HE has the same footprint and compact one-box format and user friendly operating software as existing Astrella amplifier products. It is available with a choice of 35 fs or 100 fs pulse widths.

Like other Astrella amplifiers, the new Astrella HE integrates a titanium:sapphire oscillator and a single-stage regenerative amplifier together with a pulsed green (527 nm) laser to pump the amplifier stage – all in a single box measuring only 1247 mm x 755 mm x 262 mm. A major challenge in power/energy scaling of titanium:sapphire laser amplifiers is heat management, specifically cooling the gain crystal. By clever design optimization, Astrella HE delivers higher pulse energy than any other kilohertz regenerative amplifier as well as excellent beam quality: M² ≤ 1.25. In addition to state-of-the-art performance, Astrella also provides industrial 24/7 reliability and stability because it is designed from the ground-up under the Coherent HALT/HASS program (Highly Accelerated Life Testing and Highly Accelerated Stress Screening).

The Astrella HE can be used to pump multiple tunable optical parametric amplifiers (OPAs) either to simultaneously run multiple experiments, or single experiments that need multiple independently tunable wavelengths. Astrella HE decreases dramatically the entry barrier to applications so far addressed by complex and more expensive multi-box ultrafast amplifiers. Applications like EUV generation approaching the water window or laser plasma acceleration can now be addressed by a compact UF amplifier, resulting in a cost-effective, compact, and reliable set-up. In turn, this will enable applications of EUV coherent radiation or energetic electrons to industrial diagnostics, biology, material science, and microelectronics.

Introducing the First Switchable Adjustable Ring Mode (ARM) Fiber Laser

Santa Clara, CA, November 11, 2019 – The new Coherent HighLight^TM FL-ARM with Fiber-Fiber-Switch is a high-power (2 - 8 kW), dual fiber output laser that can sequentially power two separate workstations or processes. Dual fiber output delivers increased throughput in cost sensitive, high-volume welding applications, particularly in automotive manufacturing, such as welding of doors, hang-on parts, ultra-high strength steel components, and aluminum body frames. Alternately, the second fiber can act as a redundant backup for the first, thus minimizing service downtime when required.

HighLight FL-ARM implements power sharing through the use of Coherent’s proprietary Fiber-Fiber-Switch technology. The process fibers themselves utilize Coherent’s unique Adjustable Ring Mode configuration, comprising a dual core delivery fiber which produces a central spot surrounded by another concentric ring of laser light. The power levels in the center and the ring can be independently adjusted on demand (from 1% to 100%) and switched at a rate 1000 times faster than competing products; it can also be independently modulated. This arrangement provides improved control of keyhole and melt pool stability during the welding process, leading to superior results. Added to this, HighLight FL-ARM employs a multi-stage back reflection immunity system that enhances laser reliability and lifetime, and enables safe processing of highly reflective materials, including brass, copper, and aluminum.

The HighLight FL-ARM with Fiber-Fiber-Switch is the first new product to be introduced by the recently created Coherent Center of Excellence for fiber lasers in Tampere, Finland.

Its unique combination of high speed, large marking field, ability to produce individual marks, and powerful control software make it well suited for marking ICs with serialization codes, performance specifications, traceability data, and anti-counterfeiting features.

The PowerLine E Twin is a Class IV laser sub-system comprising two diode-pumped solid-state lasers, two galvanometer scanners, and all associated drive electronics, control software, and chiller. The combination of twin lasers and scanners can simultaneously produce two different marks on a single work piece (which may consist of several, individual ICs on strip, tray or wafer-level). Additionally, it can cover a marking field as large as a 300 mm wafer or JEDEC tray, thus delivering double the effective marking speed of traditional, single laser products. With the PowerLine E Twin, the control of the independent lasers and scanners occurs internally; the operator just sees a single, easy-to-use interface that efficiently translates job specifications into the necessary operating instructions. The software also includes Matrix Object functionality; this enables it to use supplied part position data to mark arrays of products, such as multiple ICs at the wafer-level, in strips, or in handling trays.

The PowerLine E Twin is designed for easy integration, and is meant to be a straightforward replacement for single laser markers. For example, it avoids the cost of unnecessary duplication and utilizes only one power supply and chiller, and incorporates lasers and scanners in a single mechanical assembly. Moreover, the system integrator can rely on Coherent’s application expertise to develop and refine processes and optimize laser system parameters, thus taking maximum advantage of the higher speed and operational flexibility offered by the PowerLine E Twin.

New Ultrafast Laser Broadens Horizons for Multiphoton Imaging

Santa Clara, CA, 10/19/2019 – The unique performance of the new Chameleon Discovery NX laser delivers deep multiphoton microscope images with superb brightness and high contrast, making it especially well-suited for live tissue imaging in neuroscience and other intravital applications.

The Chameleon Discovery NX offers breakthrough power levels (up to 3 W), and shortest pulses at the sample plane to enable complex two photon microscope configurations. Short pulse duration is key to high brightness/contrast images and is enabled by a group dispersion delay (GDD) pre-compensator with enhanced dynamic range. It avoids unwanted pulse stretching, even in wide field microscope setups using highly refractive objectives, allowing users to minimize unwanted sample heating and maximize image depth.

Chameleon Discovery NX provides several other industry-leading benefits: It boasts tuning from 660 nm to 1320 nm, while simultaneously producing a high-power fixed wavelength output at 1040 nm. It is also available with Total Power Control (TPC), enabling built-in high-speed power modulation. Incorporating the latest acousto-optic (AO) technology, this functionality provides high-contrast modulation on both the tunable femtosecond output and the 1040 nm output. TPC ensures that the laser’s excellent beam quality is delivered directly to the microscope scan head.

Furthermore, real-time power modulation provided by TPC is important in multiphoton microscopy for several reasons. It enables optimization of laser power for each image plane depth, and for fast “flyback” beam blanking when unidirectional raster scanning is required. The TPC function provides fast rise-time, and both analog and digital control of laser power, which may be synchronized with the microscope scanning optics.

In addition to multiphoton imaging, the Chameleon Discovery NX is well suited to ultrafast spectroscopy and other time-resolved studies. Its utility in these applications can be expanded with optional frequency extensions which broaden the wavelength coverage from 330 nm to 16 μm.

HyperRapid NXT: Advanced Pulse Synchronization Improves Picosecond Laser Micromachining

Santa Clara, CA, June 24, 2019 – The Coherent HyperRapid NXT is a high-power picosecond laser that employs advanced pulsing technology to enable micromachining with precision and a minimal heat affected zone (HAZ). Specifically, HyperRapid NXT implements Coherent’s PulseEQ technology, which delivers strings of synchronous, invariant pulses on demand from an external trigger signal. This jitterfree, precision triggering and advanced energy control enables system builders to benefit from the highspeed synchronization capabilities now available from state-of-the-art scanners and stages.

HyperRapid NXT is a family of picosecond (pulsewidth <15 ps) lasers available in IR, Green and UV wavelengths, at a variety of output powers. This includes outputs of 100 W average power (250 μJ pulse energy) at 1064 nm, and 30 W average power (75 µJ pulse energy) at 355 nm. All models offer fully adjustable pulse repetition frequencies, from single shot to 5 MHz. In addition, these lasers are also designed, manufactured and tested to deliver the exceptional reliability and stability required for operation in industrial 24/7 environments.

HyperRapid NXT combines high output power, the ability to deliver targeted laser energy (regardless of scan speed), and the inherent benefits of virtually athermal picosecond processing. These characteristics make it an appropriate source for a variety of micromachining tasks that require high spatial precision and minimum HAZ. Typical applications include OLED cutting, SmartCleave® glass and sapphire filamentation cutting, and semiconductor wafer and low-κ material scribing, as well as cutting of modified polyimide (MPI) and liquid crystal polymer (LCP) – two constituents in the fabrication of 5G cellular phone antennas.

PowerMax Pro OEM: Fast OEM Laser Power Sensor Elevates In-Line Control of Critical Processes

Santa Clara, CA, June 24, 2019 – The Coherent PowerMax PRO OEM is a new laser power sensor whose large active area, fast response and high power capacity offer advantages over the semiconductor photodiodes and other detectors commonly used for continuous inline monitoring in applications having a narrow process window. Specifically, the new PowerMax PRO OEM utilizes Coherent’s patented transverse thermoelectric detector technology, which combines the response speed of a photodiode with the broadband wavelength coverage, large detection area, dynamic range, and laser damage resistance of a thermopile. This enables PowerMax PRO OEM to offer a higher performance and cost competitive alternative to photodiodes, which often require optical attenuation and complex preamplification for onboard power measurement in precision materials processing systems.

The new PowerMax model is particularly useful with CO2 lasers, where its high power handling capability, large active area (15 x 15 mm²) and broadband spectral response deliver fast, accurate and low noise measurements; plus, it eliminates the expense and complexity of the optical attenuators, preamps and TE coolers often required with photodiodes. It is also well matched for measuring ultra-short pulse industrial lasers with output in the ultraviolet, since an available coating prevents exposure related drift in detector response, such as occurs with photodiodes.

The PowerMax PRO OEM offers an attractive solution for embedded use in precision materials processing systems that operate in a highly confined process window, and therefore require constant monitoring of laser output. Typical applications include aesthetic medical systems and precision micromachining systems used in microelectronics manufacturing (e.g. via drilling), solar cell fabrication, medical device production, and various tasks in converting/packaging. In addition to the bare OEM detector, Coherent can also supply a ready to use “developer’s kit”, including cables, housing, and software integration.

Axon: Compact Ultrafast Laser Lowers Costs for Microscopy and Other Applications

Santa Clara, CA, June 24, 2019 – Coherent has introduced the Axon family, a completely new suite of compact femtosecond lasers, designed from inception to deliver lower cost, reduced complexity, and smaller footprint. Axon addresses demanding applications such as multiphoton microscopy (MPE), nanoprocessing, semiconductor metrology, and THz spectroscopy. Axon is a fixed wavelength, compact (212 mm x 312 mm x 62 mm), air-cooled laser delivered at a market-enabling price point. The first two models have output wavelengths of 920 nm and 1064 nm, with other wavelength versions expected soon. All Axon lasers feature the same form, fit and function, including 1 W of average power with integrated, software-controlled GVD pre-compensation. To further simply adoption of this laser, its output matches the existing femtosecond laser oscillators: short (< 150 fs) pulse width, a clean temporal profile and 80 MHz pulse repetition rate.

A major application of the Axon lasers is multiphoton microscopy. The 920 nm laser is designed for GFP and related imaging probes, and Ca2+ indicators such as GCAMP. The 1064 nm version matches well with red shifted Ca2+ indicators and red fluorescent proteins. Although MPE delivers inherent 3D images, deep penetration and high cell viability, market adoption lags well behind confocal microscopy because the cost and size of available femtosecond lasers and the challenges of integrating them with a microscope. The combination of the optional integrated fast modulation and small laser head allows for direct attachment of Axon to a microscope scan head, potentially negating the need for an optical table. Other applications for Axon include two-photon polymerization, material nanoprocessing and semiconductor and thin film metrology. The 1064 nm model is also an excellent tool for supercontinuum generation thanks to its high fidelity femtosecond pulse quality.

Director of Product Marketing, Darryl McCoy, notes that, “The short pulse width and high peak power of femtosecond lasers enable cutting-edge methods in biology, physics, applied science, semiconductor metrology and materials processing. We are committed to supporting developers in these important fields with lasers that offer a combination of performance, ease of use and economy in order to enable the widest possible user base. We are proud to introduce a new generation of laser that exemplifies this commitment.”

Monaco UV: Introducing High Reliability, Industrial UV Femtosecond Laser for Precision Cutting

Santa Clara, CA, June 24, 2019 – The new Coherent Monaco UV femtosecond laser provides industrial 24/7 reliability with the energy, repetition rate, and resulting minimal heat affected zone (HAZ) to drive high-throughput, high-precision cutting, scribing, and drilling in microelectronics. This makes the laser suitable for OLED cutting, wafer cutting, cutting of thin polymer films and foils, flex circuit and low-κ material processing.

While UV (345 nm) femtosecond lasers deliver lower HAZ than other ultrashort pulse lasers, their deployment into the industrial market has been slowed by unsatisfactory reliability. In contrast, Monaco UV utilizes the rigorous HALT/HASS design, manufacturing, and testing protocols employed in the company’s other high-reliability ultrafast and UV lasers. It is the first UV femtosecond laser which offers greater than 3X reduction in HAZ, while simultaneously delivering Coherent’s hallmark industrial reliability.

In addition to exceptional reliability, the output of the Coherent Monaco UV has been specifically designed to deliver the combination of pulse energy and repetition rate (20 µJ/pulse at 1.25 MHz) that best matches the ablation threshold of commonly utilized materials. This enables it to enhance production throughput, while simultaneously offering a lower cost per watt than competitive lasers. And, the monolithic Monaco UV is also the most compact (L=963 mm x W=358 mm x H=175 mm) industrial femtosecond UV solution available, simplifying integration for the system builder. Additionally, the Monaco UV utilizes the same powerful software interface as the rest of the Monaco family, making it easy for both the systems integrator and end user to migrate to this new source.

Coherent THz-Raman® Modules Reveal Sample Phase Morphology

Santa Clara, CA, February 1, 2019 – The Coherent TR-Series of THz-Raman® spectroscopy modules deliver spectral information in the THz frequency (i.e., low wavenumber) range, which provides unique data about subtle phase differences, crystallinity, orientation and other sample characteristics. TR-Series modules can be used to upgrade an optical microscope or virtually any visible/NIR or Raman spectrometer. These products allow simple access to this key “structural fingerprint” frequency range, and enable non-destructive characterization of structural changes in real time. Coherent will display these TR-Series modules at their upcoming BiOS and Photonics West exhibits (San Francisco, February 2-3, and 5-7, 2019, respectively).

Coherent TR-Series modules utilize the company’s patented narrowband filter technology. Specifically, these notch filters are reflective volume holographic filters (VHGs) that are engineered to deliver long lifetime, high efficiency and excellent transmission. Their bandwidth is a factor of ten narrower than legacy gel-based holographic or thin film notch filters, enabling the capture of both Stokes and antiStokes Raman scatter very close to the laser excitation wavelength.

In spite of its unique potential, research and imaging based on the THz spectral region has been limited mainly to specialty laboratories. Because of the complexity and cost of the systems needed to generate and detect THz radiation, frequency-resolved THz data has been even more challenging. However, by using Raman scatter near to the excitation (Rayleigh) wavelength, these TR-Series modules now provide the same data, but with the convenience and affordability of using visible or near-IR light, i.e., with glass optics, fibers and silicon-based (CCD/CMOS) detectors.

These new products for Raman spectroscopy expand and complement Coherent’s comprehensive portfolio of lasers and laser systems for life science applications that address scanning microscopy and flow cytometry.

Coherent Introduces New QBH Format, Air-Cooled Fiber Optic Cables

Santa Clara, California, June 26, 2017 – Coherent (formerly Optoskand AB) has introduced RQB Fiber Optic Cables – new air-cooled, beam delivery, fiber optic cables with a standard QBH interface, for use with fiber lasers operating at CW power levels up to 1.5 kW (and pulsed lasers as high as 1 MW). This makes these new cables an attractive option for cost sensitive applications level, and also enhances system simplicity when utilized with air-cooled fiber lasers.

RQB Fiber Optic Cables incorporate quartz block technology, which enables the use of anti-reflection coatings to reduce overall losses to under 3%. Additionally, these cables feature a mode stripper to prevent unwanted back reflections or pump light from propagating in the cladding, as well as an integrated thermoswitch in the connector to protect against overheating. They also include a safety interlock that continuously monitors the status of the fiber. RQB Fiber Optic Cables are available with core diameters from 50 µm to 1000 µm, a 0.20 numerical aperture, in lengths of 5 m to 200 m.

The use of external water cooling extends the RQB maximum power rating to 3 kW. Plus, the option of a square cross-section core delivers an essentially “flat-top” square beam with dimensions ranging from 100 µm x 100 μm to 1000 µm x 1000 μm.

New Fiber to Fiber Coupler with Power Handling Capability of 12 kW (CW)

Santa Clara, California, June 26, 2017 – A new Fiber to Fiber Coupler (FFC) from Coherent (formerly Optoskand AB) enables the use of replaceable, process fiber optic cables so that integral components of the fiber laser – most notably the feeding fiber – are not exposed to opto-mechanical damage, even in harsh industrial processes. Damage to the feeding fiber means long and often costly down time. But the new FFC enables the use of a separate fiber interface, and this separate delivery fiber can be exchanged in minutes in the case of damage.

The FFC is an eye-safe, stand-alone, water-cooled photonic component that handles laser power levels of 12 kW. A range of options enables coupling between fibers of different core diameters, as well as commonly used connector interfaces (QB, QD and Q5).

The FFC incorporates DGUV-certified safety electronics, and is an extension of the feeding fiber interlock circuit. It also includes integrated sensors, monitored and controlled by CANopen communication, whose threshold values can be set to enable or disable the interlock circuitry.

The FFC is ideal for high power industrial applications of fiber lasers, including Coherent HighLight FL series products.

New Visible Diode Laser Modules Feature High CW Power and Superior Beam Quality

Santa Clara, California, January 30, 2017 –Coherent has expanded their DILAS family of CW, fiber-coupled diode laser modules with two new visible wavelengths – delivering 2 watts at 520 nm (green) and 1.4 watts at 638 nm (red). Because these OEM modules are based on Coherent | DILAS’ unique, multi-single- emitter technology, they provide high optical efficiency and excellent beam quality. They are both offered with SMA connectors for 200 µm fiber having a 0.22 numerical aperture (NA) to enable simple collimation, as well as tight focusing to a small, high-intensity beam waist. The combination of compact (17 mm x 30 mm x 62 mm) packaging, fiber coupling, conduction cooling, and an internal NTC temperature sensor simplifies integration into a broad range of instruments and systems across life sciences, machine vision, and other OEM applications.

These unique DILAS modules avoid the well-known trade-off between power and coupling efficiency by imaging the output of several single emitters into one fiber using proprietary beam combining and shaping optics. The result is a module with the coupling efficiency and output quality of a single emitter, but with the higher power of a multi-emitter bar. These new modules are supplied in housings that are optomechnically identical to the existing ultraviolet (405 nm) and blue (450 nm) modules.

By extending the range of this modular platform from the UV through the RGB spectrum, these new high performance visible lasers are ideal for numerous photonic and biophotonic applications requiring multiple watts of green or red visible light. Examples include confocal microscopy, drug discovery, array readers, multi-wavelength flow cytometry, photodynamic therapy (PDT), white light generation, and pumping titanium:sapphire lasers.

New Femtosecond Lasers Offer Higher Pulse Energy and Higher Repetition Rates

Santa Clara, California, January, 30 2017 –Coherent has significantly extended the performance of their Monaco series of industrial-grade femtosecond lasers by increasing their adjustable pulse repetition rate to a maximum of 50 MHz. Plus, the company has launched a new high energy Monaco that provides up to 60 µJ/pulse in the near infrared (1035 nm), or, optionally 30 µJ in the green (517 nm). These improvements provide enhanced performance in precision materials processing applications, particularly for delicate and/or tough materials, and also deliver increased frame rates in demanding multiphoton microscopy imaging applications. All Monaco lasers produce a high quality (M2 < 1.2) beam, enabling tight focusing for high brightness and high spatial resolution. Additionally, the pulsewidth can be user set from under 400 fs to over 10 ps.

The improved Monaco 1035-40 provides 40 watts of average power in the near-IR (1035 nm), with the user selecting pulse repetition rates of 1, 2, 3, 4, 5, 10, and 50 MHz from a simple pull-down menu in the laser GUI, with no effect on output pulsewidth. The Monaco 517-20 provides 20 watts of green output with the same operational and output specifications. The all-new infrared Monaco 1035-60 and green Monaco 517-30 provide an additional operating point at 670 kHz for users requiring very high pulse energy: 60 µJ in the near-IR, and 30 µJ in the green. These lasers are ideal for cutting thicker substrates and drilling deep holes in ceramics, glass, and materials used for bio-absorbable stents. The short pulsewidth ensures excellent edge and surface quality without the need for post-processing steps in most applications.

In bio-imaging applications, these high repetition rate lasers enable higher frame rates than competitive products, particularly for power hungry applications such as photoactivation in optogenetic experiments. Here, the near-IR output can be used directly for two-photon excitation of red fluorophores such as mFruits. Or it can also be used to pump the Opera-F, a variable pulsewidth optical parameter amplifier (OPA) that then provides smoothly tunable output across the entire microscopy imaging spectral window.

Higher Power Nanosecond Lasers Cut Thicker Films, PCBs, and Flex Substrates

Santa Clara, California, January 30, 2017 – New, high power ultraviolet (355 nm) and green (532 nm) additions to Coherent’s popular AVIA industrial nanosecond laser family extend and improve the performance of microprocessing applications in microelectronics, photovoltaics and related industries. Specifically, the new AVIA 355-55 features a very high (150 kHz) pulse repetition rate, resulting in an average power of 55 watts at 355 nm. The AVIA 532-80 produces high (1 millijoule) pulse energy, which, together with a maximum pulse repetition rate of 80 kHz, translates into an average power of 80 watts.

Coherent AVIA lasers are compact, rugged, vanadate lasers that are well-established in many microprocessing applications because of their superior performance. Just as important, they deliver unmatched reliability and longevity through the use of Highly Accelerated Life Testing (HALT) protocols, which identify failure mechanisms so that they can be designed out. Then, individual production units are tested using Highly Accelerated Stress Screening (HASS) methods. Coherent is the only laser manufacturer to employ this stringent HALT/HASS stress testing methodology, which identifies and eliminates any potential reliability issues with products before they are shipped to the customer, without decreasing their useful life. This minimizes cost of ownership for these lasers.

AVIA ultraviolet lasers are used for cutting flex substrates and thin printed circuit boards (PCBs) where higher lateral resolution (i.e., precision xy features) are a critical consideration. The higher power now available from the new AVIA 355-55 will extend these cutting capabilities to thicker (> 200 µm) flex and multi-layer materials. It will also enable existing applications to be accelerated to higher throughputs, while still delivering the same superior edge quality with minimal peripheral thermal damage.

AVIA green lasers are used for scribing films, drilling holes and slots, and cutting flex substrates that efficiently absorb green wavelengths, including certain PCB substrates, semiconductors, and photovoltaic components. The unique, high pulse energy of the new AVIA 532-80 provides high piercing capabilities for drilling, cutting and scribing, deeper features and thicker substrates than competitive lasers. And the 80 kHz repetition rate ensures high process throughput.

High Power Pulsed Fiber Laser Enables Precision Material Removal

Santa Clara, California, January, 30, 2017 – A new, 1 kW (average power) pulsed fiber laser from Coherent | Rofin offers the highest beam quality currently available at this power level, thus enabling high throughput, precision ablation for a variety of industrial and solar applications. Specifically, the FP 010 delivers a maximum pulse energy of 100 mJ, at pulse widths between 10 ns and 100 ns, and with repetition rates ranging from 10 kHz to 30 kHz. A beam parameter product of < 24 mm x mrad (for a 400 μm, round core output fiber) enables this power to be effectively concentrated into small focused spot sizes. The result is the ability to achieve a higher power focused spot at a given distance than other pulsed fiber lasers, or to achieve the same spot size, but at a longer working distance or over a larger scanning field.

In addition, the Coherent | Rofin FP 010 is constructed to deliver exceptional reliability and high uptime in demanding, multi-shift industrial environments. This is achieved, in part, by using the same, field-proven components as employed in the company’s standard, CW fiber laser products. Also, the use of pump laser bars having a wide emitter separation minimizes the impact of a single diode failure on overall system operation.

The unique combination high average power, high pulse energy and superior beam quality makes the FP 010 an ideal source for ablation, surface cleaning, and precision material and coating removal in a range of applications. These include AlSi removal from tailored blank parts prior to welding, edge deletion for thin film (CdTe, CIGS) solar cells, cleaning of molds, aerospace components and other precision parts, as well as other surface cleaning, activation and structuring uses.

Founded in 1966, Coherent, Inc. is one of the world’s leading providers of lasers and laser-based technology for scientific, commercial and industrial customers. Our common stock is listed on the Nasdaq Global Select Market and is part of the Russell 1000 and Standard & Poor’s MidCap 400 Index.

OPA Delivers Short Pulsewidth and Wide Tuning

Santa Clara, California, February 12, 2016 – The Opera-F is a new optical parametric amplifier (OPA) from Coherent, Inc. (Santa Clara, CA) that delivers wide tuning, high conversion efficiency, and sub-100 fs pulse duration when pumped by the company’s Monaco high performance ytterbium ultrafast amplifier. The signal output of the Opera-F is tunable from 650 nm to 900 nm, and the idler is tunable from 1200 nm to 2500 nm. When pumped by the Monaco at 40 Watts, the Opera-F provides the industry’s highest power (up to 3 Watts) and highest pulse energy (up to 3 µJ) as well as an industry leading 1 MHz maximum pulse repetition rate. These characteristics make it the optimum tunable source for scientific experiments needing high data acquisition rates or a high level of signal averaging.

Ytterbium-based amplifiers feature several advantages over Titanium:Sapphire alternatives, including direct diode pumping and simplified architectures. However, ytterbium amplifiers usually have longer pulsewidths. This difference has been eliminated with the Opera-F, a single-box accessory which includes a non-collinear stage to generate pulsewidths as short as 50 fs, followed by a collinear stage which delivers very broad wavelength tuning. The output wavelength is tuned through software, with no physical adjustment required.

The high power and high repetition rate of the Opera-F are ideal for advanced multiphoton microscopy studies in neuroscience; the high power is a particular advantage for multi-beam imaging setups using a spatial light modulator (SLM). It is equally well-suited to liquid phase pump-probe experiments including solvation mechanics and studies of advanced solid state materials for light harvesting, displays and semiconductor industry.

High Brightness Taipan HD Lasers

Santa Clara, California, February 12, 2016 – An expanded series of light show and entertainment lasers from Coherent, Inc. (Santa Clara, CA) enable show designers to produce sophisticated visual displays and effects with increased brightness and better definition. Specifically, the company’s newest Genesis Taipan HD series lasers all offer TEM00 beam characteristics, and are available with powers between 2 and 5W at six standard Taipan wavelengths (460 nm, 480 nm, 488 nm, 532 nm, 577 nm, and 590 nm) matching most of the standard Taipan Multitransverse Mode (MTM) product line. This wide selection of wavelengths enables laser projectors to deliver a full palette of primary colors, plus tinted white and mixed colors, such as D65 white. All Genesis Taipan HD products have the same compact footprint and low electrical/thermal budget as other Taipan lasers, as well as the usual 50 kHz direction modulation, simplifying their integration in existing projectors.

The TEM00 output beam of Taipan HD lasers is critical to their ability to produce sharper displays. Specifically, this type of output delivers the possibility for diffraction limited divergence resulting in the smallest achievable projected spot size, and hence the highest possible brightness. In contrast, most light show lasers generate a so-called multi-transverse mode beam, which produces much larger, irregular and dimmer projected spots or graphics, especially if multiple laser diode emitters or laser sources were used and beam-combined. Preliminary testing indicates 1.8X increase in brightness for the Taipan HD laser over other sources. In addition, their smooth Gaussian beam profile enables white displays with the absolute minimum of color fringing.

All Coherent Genesis Taipan lasers are based on the company’s unique optically pumped semiconductor laser (OPSL) technology. Characterized by scalable power and wavelength as well as high unit to unit consistency, this all solid state technology has been proven to be the most reliable visible laser type anywhere, with tens of thousands of units in the field.

Coherent distributes the Taipan product line via certified integrators only. For more information refer to http://www.coherent.com/products/?1610/Coherent-Certified-Integrators.

Industrial Femtosecond Green Laser for Superior Materials Proc

Santa Clara, California, February 12, 2016 – Coherent has extended the capabilities of their Monaco family of industrial femtosecond lasers with the first model delivering visible (green) output, thereby enabling superior processing of a wider range of materials. The new Monaco 517 is a fiber-based laser that produces 20 watts at 517 nm, and combines short (<400 fs) pulsewidth and high (20 µJ) pulse energy to generate the high peak intensity needed for precision micromachining of “tough” materials like polymers. Plus, the laser’s MHz pulse repetition rate supports fast throughput. The Monaco 517 is also simple to integrate into any OEM system because its self-contained compact laser head measures only 635 mm x 340 mm x 167mm. Moreover, the monolithic construction of the laser means that optimum alignment is maintained throughout its entire lifetime, thus maximizing its value and utility for end users and OEMs alike.

Green output delivers three key advantages for materials processing in industries like microelectronics and display fabrication. First, it yields a lower ablation threshold than longer wavelengths, thereby expanding the range of materials and thicknesses that can be athermally processed. Next, the shorter wavelength allows smaller focused spots, enabling finer features to be created. Finally, several materials, including important semiconductors, have improved absorption properties in the green, so this wavelength maximizes cutting efficiency and depth control.

The Monaco 517 is ideal for a range of micromachining applications in the semiconductor, flat panel display, solar, and microelectronics industries. It is well-suited for processing metal and non-metal thin films and foils, and for scribing conductive oxides and semiconductors. In addition to processing homogeneous materials, such as glass and metals, the material versatility of the Monaco 517 makes it an optimum tool for drilling, cutting and patterning complex, layered-structures.

Monaco has been developed as part of The Industrial Revolution in Ultrafast Science, which is redefining customer expectations of performance and reliability for laser technology. By employing a rigorous, multifaceted HALT/HASS protocol in the design, engineering, and manufacturing of our ultrafast products, the customer receives a product with certified reliability and performance, irrespective of the intended use. It’s cutting-edge testing for cutting-edge performance.
