- Model RYB series - Solid State Raman Shifter



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.

  1. The parameters marked typical are not specifications. They are indications of typical performance and might vary unit-to-unit. Unless stated otherwise all specifications are measured at 1064 nm at 10 Hz pulse repetition rate.
  2. Most of Nd:YAG actively Q-switched would be suitable for pumping wavelength converter. Please provide specifications of your laser.
  3. When pumped by Nd:YAG laser. For Nd:YLF lasers the wavelength is different. Converter produces factory-set single wavelength output. Inquire for simultaneous multi-wavelength output specifications.
  4. Indicated values are typical and were measured with our Quantas series lasers.
  5. Full angle measured at 1/e2 level.
  6. FWHM level at 1064 nm.
  7. Averaged from 500 pulses.
  8. Averaged from 500 pulses.
  9. Adaptation to user pump laser might be required. Dimensions indicated here are valid when pumped by Quantas series laser.
  10. Condensation of water vapor should be prevented on optical and electrical components.
