报道了半导体激光端面抽运Nd：YAP晶体产生的1080 nm基频光驱动纯YVO₄晶体的被动调Q拉曼激光特性。利用初始透过率85%的Cr⁴⁺：YAG/YAG复合晶体作为可饱和吸收体，以a切YVO₄晶体的890 cm^-1拉曼频移为研究对象，研究了一阶斯托克斯光的输出功率和脉冲特性。在抽运功率为9.87 W时，获得了平均输出功率0.76 W的1195 nm一阶斯托克斯光，转化效率为7.7%。脉冲重复频率从阈值附近约3.7 kHz持续增加至33.5 kHz。最高抽运功率下，脉冲宽度为1.5 ns，对应最大单脉冲能量为22.8 μJ，最高峰值功率为15.2 kW。

The output characteristics of passively Q-switched YVO₄ Raman laser derived by a diode end-pumped Nd：YAP laser at 1080 nm was investigated. A Cr⁴⁺：YAG/YAG composite crystal with an initial transmittance of 85% was used as saturable absorber. The first-Stokes wave output power and pulse characteristics based on a-cut YVO₄ crystal with the Raman shift of 890 cm^-1 were studied. Under an incident pump power of 9.87 W， the average output power of 0.76W and conversion efficiency of 7.7% were obtained for the first-Stokes wave. The pulse repetition frequency rose from 3.7 to 33.5 kHz as the incident pump power increased from threshold to 9.87 W. The pulse width was about 1.5 ns at the maximum incident pump power. Therefore， the corresponding maximum single pulse energy and peak power were 22.8 μJ and 15.2 kW， respectively.
