以Cr:YAG兼作可饱和吸收体和耦合输出镜，实现了激光二极管(LD)端面抽运Nd:LuVO4晶体的微片式被动调Q激光。当抽运功率为13.86 W时，最大平均输出功率为0.508 W，相应的光光转换效率为3.6%，斜率效率为8.3%，最高重复频率、最大单脉冲能量和最短脉冲宽度分别为23.95 kHz，21.21 μJ,4.5 ns，对应的峰值功率为4.71 kW。

With Cr:YAG as saturable absorber and output coupler, passively Q-switched microchip laser was obtained for laser diode (LD) end-pumped Nd:LuVO4 crystal. When the pump power was 13.86 W, a maximum average output power of 0.508 W was obtained, corresponding to an optical conversion efficiency of 3.6%, and a slope efficiency of 8.3%. The highest repetition rate, largest pulse energy and shortest pulse width were measured to be 23.95 kHz, 21.21 μJ, and 4.5 ns, respectively, corresponding to a peak power of 4.71 kW.
