摘要
提出了一种测量激光晶体热焦距的装置和方法,并以此设计和实现了一台采用平平腔结构激光二极管阵列侧面抽运Nd:YAG再生放大器。通过注入脉冲宽度为2ns、中心波长为1064nm、重复频率为300Hz的300pJ小信号种子光,实现了脉冲宽度为2ns,单脉冲能量1.5mJ的基横模激光输出。总放大倍数为5×106,输出能量稳定性为1.08%[方均根值(RMS)],方波扭曲度为1.10。
A new method is proposed to measure the thermal focal length of laser crystal. Based on the experimental results, a laser diode （LD） side-pumped, flat-flat cavity regenerative amplifier is developed. By injecting a small signal seed light with wavelength of 1064 nm, pulse width of 2 ns, repetition rate of 300 Hz and pulse energy of 300 pJ, the output TEM00 laser with maximum pulse energy of 1. 5 mJ, pulse width of 2 ns is obtained. The corresponding amplification ratio is 5 X 106 , and the output energy stability is 1.08% [root-mean-square （RMS）] with the square-pulse distortion of 1.10.
