摘　　要：将KTiOAsO4(KTA)Stokes参量振荡器置于LD侧面泵浦的1064 nm调Q Nd^3+:YAG谐振腔内,通过KTA晶体的非共线受激电磁耦子散射获得在1078.20~1088.20 nm范围内不连续调谐的Stokes激光。该Stokes激光又作为共线拉曼激光器的泵浦源在同一块KTA晶体中实现了受激拉曼散射,通过设计Stokes谐振腔的输出镜透过率,选择对一阶拉曼光进行输出,其在1106.08~1116.62 nm范围内不连续调谐。当LD泵浦功率为94.20 W,重复频率为5 kHz时,在1116.34 nm处得到了最大功率为1.62 W的拉曼激光输出。A KTiOAsO4(KTA)Stokes parametric oscillator is placed in the cavity of a laser diode(LD)side-pumped Q-switched 1064-nm Nd^3+:YAG resonant cavity.By non-collinear stimulated polariton scattering in the KTA crystal,a Stokes laser with discontinuously tuned wavelength in the range of 1078.20-1088.20 nm is obtained herein.This Stokes laser is used as the pump source of a collinear Raman lasers to achieve stimulated Raman scattering in the same KTA crystal.The output mirror transmittance of the Stokes resonant cavity is designed to output the first-order Raman laser with discontinuous tunability in the range of 1106.08-1116.62 nm.At an LD pump power of 94.20 W and a pulse repetition frequency of 5 kHz,a 1116.34-nm Raman laser with a maximum power of 1.62 W is obtained.
