Abstract
A second-Stokes Raman laser based on with a wavelength pumped by an Nd:YAG laser at scattered at phonon was developed. High-reflection mirrors for the Stokes wavelength were used. The maximum output energy was 0.85 mJ. The conversion efficiency increased with crystal length of 40–100 mm up to 30%. The spatial beam profile was smooth, and the Raman laser emission lasted for . New stimulated Raman scattering lines from a phonon at were observed.
