The stimulated Raman scattering (SRS) of 532 nm, 30 ps pulse was investigated in YVO4 crystal samples. In an external single-pass configuration, the SRS thresholds for the first Stokes line were measured for different crystal lengths, and the steady-state gain coefficient was calculated to be 16.0±0.5 cm/GW. In this experiment, the second Stokes line (558.6 nm, 587.8 nm) as well as the first anti-Stokes line (508.0 nm) was also observed. The total conversion efficiency of SRS was higher than 50%.
