Abstract Stimulated Raman scattering (SRS) of picosecond pulses is investigated in a new crystal SrWO4. The second harmonic generation of a mode-locked Nd:YAG laser system is used as the pump source. In an external single-pass configuration, the SRS thresholds for the first to the fourth Stokes lines are measured. For the first Stokes line, the steady-state gain coefficient of the SrWO4 crystal is calculated to be 15.96cm/GW. In our experiment, as many as five Stokes lines (559.23nm, 589.61nm, 623.49nm, 661.50nm, 704.44nm) and three anti-Stokes lines (506.97nm, 484.34nm, 463.65nm) are observed, and the total conversion efficiency is as high as 62%.
