Abstract

Stimulated Raman scattering (SRS) has been observed in various crystals generating a multitude of wavelengths covering the range from 280 nm to 3 μm with a mean spacing of 1 nm. Barium nitrate crystals pumped by two different pulsed Nd:YAG laser systems have been used to demonstrate Raman laser action achieving a high average power of 5 W or an output energy of up to 23 mJ with a quantum efficiency of 43% at 1.599 μm intended for CO₂ detection in longrange LIDAR systems. Spectral narrowing of the pump radiation reduced the Raman laser emission bandwidth to 0.08 cm^-1.
