Abstract

A second-Stokes Raman laser based on PbWO4 with a 1.316-µm wavelength pumped by an 120-ps Nd:YAG laser at 1.06415 µm scattered at 901 cm-1 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 18 ns. New stimulated Raman scattering lines from a phonon at 323 cm-1 were observed.
