GWU-Lasertechnik has more than 30 years of experience in lasers and nonlinear optics. We are the pioneer of commercial BBO OPO technology. Our widely tunable pulsed laser sources cover the spectral range from the deep-UV at <190 nm to the IR at >2700 nm continuously. The scanSeries nanosecond product line offers scalable pulse energy at various repetition rates. As a unique feature, GWU can provide high-speed wavelength scanning across the complete wavelength range with shot-to-shot dynamic. Our all-solid-state laser design ensures maximum reliability for diode-pumped and flash-lamp pumped Q-switched lasers.

HÜBNER Photonics offer pulsed nanosecond lasers in the Cobolt Tor Series: generating up to 0.5 mJ pulse energy, <5 ns pulse width, 7 kHz PRF. Single pulse triggerable and free running models are available.

MegaWatt Lasers's ER902 is a passively Q-switched erbium glass laser that operates at 1.54 μmm. This eye-safe wavelength is ideal for defense, LIBS, and LIDAR applications. The design allows for 10 Hz repetition rates with a 4 ns pulse width and a 200 μJ pulse energy. All in a 9 mm diameter by 20 mm length package.
