研究了高功率半导体激光器抽运的Nd：GdVO_4固体激光器，采用Co ~（2+）：LaMgAl_（11）O_（19）可饱和吸收体，在1.34 μm波长处实现被动调Q。在最佳输出耦合器透过率T=5.5%，抽运功率11.5W时，获得了3.01W的静态输出功率。以Co：LMA（初始透过率T0=90%）为饱和吸收体的被动调Q实验表明，最短输出脉宽为32 ns，最高输出功率为266 mW，最高脉冲重复频率为277 kHz，最高脉冲峰值功率为187 W。
We investigated a high power diode-laser pumped passively Q-switched c-cut Nd:GdVO4 solid-state laser, lasing at 1.34 μm, with a Co2+:LaMgAl11O19 saturable absorber. With the optimum output coupler transmission T=5.5% and pump power of 11.5 W, the static output power of 3.01 W was obtained. The passively Q-switching operation with Co:LMA (initial transmission T0=90%) as saturable absorber, shows that the shortest output pulse width, the highest output power, the highest pulse repetition and the highest pulse peak power were 32 ns, 266 mW, 277 kHz, and 187 W, respectively.
