  • 采用腔外单次通过方式,研究了一种新型晶体YbVO4的受激拉曼散射.当抽运激光为532 nm皮秒脉冲时获得了3级斯托克斯线(558.47 nm, 587.92 nm, 620.67 nm)和1级反斯托克斯线(507.58 nm),测得YbVO4晶体1级斯托克斯受激拉曼散射的稳态增益系数为17.8±0.2 cm/GW,受激拉曼散射的整体转换效率达到37%.实现了YbVO4晶体对355 nm皮秒激光的受激拉曼散射,观察到1级斯托克斯线(366.1
    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.
