摘　　要：报道了以KTP晶体作为倍频介质,以Nd:YAG晶体作为激活介质,以SrWO4晶体作为拉曼介质的折叠腔型主动凋Q腔内倍频拉曼激光器的输出特性,给出了输出黄光平均功率、脉冲能量、脉冲宽度随激光二极管(LD)抽运功率及脉冲重复率的变化关系。在输入抽运功率为12.6 W,脉冲重复率为20 kHz时,获得了1.4 W的590 nm激光输出,从LD到黄光的转换效率为11.1%。在输入抽运功率为12.6 W,脉冲重复率为10 kHz时,单脉冲能量为122μJ,脉冲宽度为4.0 ns,相应的脉冲峰值功率为30.5 kW。We present the characteristics of a folded-cavity actively Q-switched intracavity frequency-doubled Raman laser in which a KTP crystal is used as the frequency-doubling material, an Nd ： YAG crystal is used as the gain medium and an SrWO4 crystal as the Roman medium. The dependences of the average output power, the pulse energy and width on the pulse repetition rate and incident LD pump power are given. When the incident pump power is 12. 6 W and the repetition rate is 20 kHz, the average output power is 1. 4 W, and the corresponding conversion efficiency from the diode laser to yellow laser is 11.1%. When the incident pump power is 12.6 W and the repetition rate is 10 kHz, the pulse energy is 122 μJ, the pulse width is 4.0 ns, and the corresponding peak power is 30.5 kW.
