| Abstract: | With an ultra-cavity single-pass configuration, the stimulated Raman scattering (SRS) of a new crystal YbVO4 was investigated. When the pump source was a 532 nm pico-seconds laser, as many as three Stokes lines (558.47, 587.92 and 620.67 nm) and one anti-Stokes line (507.58 nm) were observed. The steady-state Raman gain coefficient for the first Stokes line was measured to be 17.8±0.2 cm/GW, and the total conversion efficiency reached 37%. For the first time, the SRS of YbVO4 crystal for 355 nm pump laser was realized. The first Stokes line (366.11 nm) was observed, and according to the pumping thresholds, the steady-state Raman gain coefficient was determined to be 29.0±0.3 cm/GW. |
