摘要
通过采用非线性相位匹配的KTiOPO_4晶体,成功实现了使用LD泵浦的Nd∶YVO_4/Nd∶YVO_4/Nd∶YVO_4键合晶体激光器声光调Q输出泵浦的光参量振荡。当泵浦功率为8.29W,声光调制频率为30 kHz时,获得了0.92 W的1570 nm信号光的最大平均输出功率,信号光的最窄脉宽为1.04 ns,最大峰值功率为29.5 kW。光光转换效率:对1064 nm泵浦光为54.4%,而对808 nm二极管泵浦光束只有11.1%。
Using a non-critically phase-matched KTiOPO_4 crystal,an optical parametric oscillator was successfully achieved by acoustic-optic Q-switched with Nd ∶ YVO_4/Nd ∶ YVO_4/Nd ∶ YVO_4 composite crystal. Under an incident pump power of 8. 29 W and modulation frequency of 30 kHz,the maximum average output power at the signal wavelength of 1570 nm is 0. 92 W,the shortest pulse duration is 1. 04 ns for the signal wave,the maximal peak power of 29. 5 kW. The conversion efficiency to the 1064 nm Q-switched pump beam is 54. 4%,to the 808 nm diode pump beam is 11. 1%.
