摘　　要：利用LD端泵Nd:GdVO4 晶体,实现了激光器的1 063 nm连续和调Q激光输出。在连续激光输出实验中,在泵浦功率为20.2 W时,得到最高的光光转换效率为55.0%,斜效率为59.1%,此时输出功率为11.5 W;在泵浦功率为33.7 W时,得到16.7 W的最大激光输出。在调Q实验中,当重复频率为10 kHz时,获得脉宽6.5 ns,能量340μJ,峰值功率52.3 kW。当重复频率为30 kHz时,获得脉宽14.5 ns,平均输出功率5.18 W,峰值功率11.9 kW。An LD pumped high power Nd：GdVO4 laser was reported. A continuous and pulse output of 1 064 nm was obtained. In the experiment of continuous output, when the pumped power was 20.2 W, an output power of 11.5 W with a maximum optical conversion efficiency of 55.0% and a slope efficiency of 59.1 % was obtained. In the acousto-optic Q-switch experiment, when the repetition is 10 kHz, a pulse width of 6.5 ns, a peak power of 52.3 kW and an energy of 340 μJ were obtained. As the repetition was 30 kHz and the minimum pulse width was 14.5 ns, the average output power was 5.18 W.
