报道了利用半导体激光器 (LD)抽运Nd∶YVO4 晶体 ,采用声光调Q ,输出 10 6 4nm高重复频率短脉冲的固体激光器。在重复频率为 70kHz时 ,获得的最大平均输出功率为 6 45W ,光 光转换效率为 34 9% ,斜效率为37 3% ;在相同的重复频率下还获得了最短脉冲宽度 7 9ns。在重复频率为 10kHz时获得最大单脉冲能量为 2 13μJ ,峰值功率为 11 8kW。

An acousto optic Q switched diode pumped Nd∶YVO 4 laser at 1064 nm is reported here. When the repetition rate is 70 kHz, the maximum average output power of 6.45 W is obtained with an optical conversion efficiency of 34.9% and a slope efficiency of 37.3%. And the shortest pulse width of 7.9 ns is also obtained at the same repetition. The highest single pulse energy of 213 μJ with peak power of 11.8 kW is generated at 10 kHz repetition rate.
