New reliable all Solid State Raman Shifter, Quantas RYB series, employs innovative technology of KGdWO4 (shift 901.5 cm-1) crystal. The crystal’s unique properties is advantageous due to high conversion efficiency, no phase matching necessity, and easier handling compared to gaseous and liquid Raman cells. Growing number of applications in medicine, spectroscopy, defense, and research requires high intensity Q-switched pulses in blue, yellow or red wavelength range that earlier were accessible only by dye or OPO lasers. The Quantas RYB Raman shifter is designed for Nd:YAG and Nd:YLF Q-switched lasers with up to 800 mJ input beam. The nonlinear KGW crystal is placed in optimized cavity to reach highest conversion efficiency of the pump radiation. Module design is user friendly with no need of crystal adjustment. Unlike gas or liquid based Raman Shifters the Quantas RYB does not use high pressure gas cell or poisonous liquids and is safe to operate.
