Verdi G Series

Based on optically pumped semiconductor laser (OPSL) technology, the new Verdi G-Series is suited for Ti:Sapphire pumping and enables the lowest CW noise applications from 2W, 5W, 7W, 8W, 10W, 12W, 15W, 18W, and 20W of 532 nm.

High-Power Optically Pumped Semiconductor Lasers (OPSL)

The Verdi G-Series is based on OPSL technology where the rod-based gain medium is replaced with a robust and versatile semiconductor chip. OPSL output power can be changed without affecting beam parameters due to the ultra-thin gain medium (i.e. no thermal lensing issues). In addition, the short upper-state lifetime of the OPS chip removes the “green noise” problem as seen with sum frequency generated (SFG) noise in multi-longitudinal mode DPSS lasers. Single longitudinal mode options are available up to 5W. See the Verdi G-Series whitepapers for more details.

Features & Benefits

  • Wavelength and power scalability– OPSL now offers new wavelengths and power never seen before.
  • No thermal lensing – OPS chip allows power to be changed without affecting beam parameters.
  • No green noise - lowest RMS noise spec <0.02% (from 10 Hz to 100 MHz) with OPS chip’s short upper state lifetime.
  • No need for strict pumped diode wavelength control via temperature servo.
  • Inherently more reliable with fewer components and electronics design.
  • Lowest cost of ownership -The Verdi provides the lowest cost of ownership by leveraging a high efficiency resonator design, ultra reliable Coherent AAA (Aluminum free Active Area) diodes and state-of-the-art manufacturing technology.
  • Long Lifetime Pump Diode Modules
  • Verdi features state of the art AAA pump diode material. Coherent’s AAA material has the longest track record with record operating hours in the field for years. The pump diode modules are located conveniently inside the power supply and deliver pump light via a single core pump fiber to the laser head. The single core fiber homogenizes the pump beam profile over the entire module lifetime and rounds up Verdi’s leading pump diode module lifetime.
  • Performance You can Rely onVerdi is manufactured featuring PermAlign™ technology. It is the same technology we use to build our high volume instrumentation lasers such as the Sapphire. It fixes the optical components inside the laser head in a solder bonding process. Once put in place, they will never move, so nothing would have to be aligned over the entire product life time. PermAlign takes place in a clean room and once completed, laser heads are hermetically sealed to ensure your laser remains contamination free.
