Abstract

A laser diode side-pumped electro-optical Q-switched Nd:YAG green light laser with high repetition rates, short pulse width, and high peak power was demonstrated. We studied the performance of the oscillator at the repetition rates from 100 to 500 Hz. At 500 Hz, 61 mJ, 5 ns of 1064 nm infrared light pulses were obtained with an oscillator-amplifier system. The peak power of the pulse was 12 MW. By frequency doubling with a LiB(3)O(5)(LBO) crystal, 32.5 mJ, 4.6 ns of 532 nm green light was achieved, corresponding to a peak power of 7 MW. The frequency conversion efficiency was 53.3%.

摘要

展示了一种具有高重复频率、短脉冲宽度和高峰值功率的激光二极管侧面泵浦电光调Q Nd:YAG绿光激光器。我们研究了振荡器在100至500Hz重复频率下的性能。在500Hz时，利用振荡器 - 放大器系统获得了能量为61mJ、脉宽为5ns的1064nm红外光脉冲。脉冲的峰值功率为12MW。通过使用LiB(3)O(5)(LBO)晶体进行倍频，获得了能量为32.5mJ、脉宽为4.6ns的532nm绿光，对应峰值功率为7MW。频率转换效率为53.3%。
