摘　　要：本文报导了用高纯半导体材料GaAS片作为负反馈元件，以改善被动叙模Nd：YAG激光器的输出特住．理论分析了GaAs负反馈作用的原理，实验研究了胜的几何参数对激光输出特性的影响，获得了稳定的长序列初模脉冲激光输出，序列脉冲数达65个，单脉冲能量～10J，脉冲宽度＜20ps，脉冲-脉冲能量抖动＜2％．In this paper, a passively mode-locked YAG:Nd laser with an intracavity semi-conductor GaAs negative feedback element is reported- The dynamics of pulse formationis analyzed. Stable extended picosecond pluse trains are generated experimentally. Thereare about 65 pulses in each pulse train with energy of 10 per pulse and pulse durationof 20 ps(FWHM). The average deviation of shot-to-shot is 2%.
