Coherent has developed a number of CO₂ laser systems for use in the most demanding scientific, aerospace, semiconductor and research applications. These specialty CO₂ lasers are ruggedly designed for use in the most severe environments.

Our Scientific CO₂ product portfolio consists of:

EOM-10, a short-pulse Q-switched cavity-dumped laser. This RF-excited laser system delivers short-pulse (<15 ns), high pulse-repetition-frequency capability (0-100kHz) in a compact package.

GEM Select, series of frequency-tunable lasers. The GEM Select series of lasers brings unprecedented wavelength tunability between 9.2 µm and 10.8 µm, and is field-proven for use in either a laboratory or field application. Other features include PZT cavity tuning, autonomous frequency/amplitude control and a visible diode laser for easy alignment of the IR laser beam. Developed over years of testing under severe operating conditions, and designed to be user-friendly, the GEM Select lasers offer high beam quality and high stability to meet the most demanding requirements.

MID-IR, a frequency-doubled laser operating around 5 microns. The MID-IR is an RF-excited, frequency-doubled, CO₂ waveguide laser system that delivers short-pulse, high pulse-repetition-frequency capability at mid-IR wavelengths (4.6 microns - 5.8 microns).

SIFIR-50, an optically pumped far-infrared (FIR) laser. Our THz laser technology utilizes many aspects of our highly reliable, sealed-resonator technology to produce compact, dependable, turn-key systems, and includes patented intellectual property. Our optically-pumped THz laser is tunable from 40 µm -1020µm (7 to 0.3 THz), consisting of a sealed-off pump laser, a frequency standard, and a THz laser cavity. The pump laser inside the SIFIR-50 features an efficient, folded resonator contained within all-metal housing.
