摘　　要：报道了用两个１．５Ｗ激光二极管偏振耦合端面泵浦的声光调Ｑ内腔倍频Ｎｄ：ＹＡＧ激光器。输出５３２ｎｍ绿光重复频率１ｋＨｚ时，最大峰值功率为２．２３ｋＷ，最窄脉宽为１８ｎｓ，平均功率４０ｍＷ。最高重复频率３０ｋＨｚ。重复频率１５ｋＨｚ时，最高平均功率１２８ｍＷ．对声光调Ｑ内倍频Ｎｄ：ＹＡＧ激光器的动态特性进行了理论分析及计算。A Q-switched intracavity frequency doubled Nd: YAG laser end pumped by two POlarization-coupled 1. 5 W laser diodes is reported. The maximum peak power of 2.23 kW at 532 nm with the pulse width of 18 ns and the repetition rate of 1 kHz is obtained. The highest repetition rate is 30 kHz, and the maximum average output power is 128 mW for the 532 nm laser at repetition rate of 15 kHz. The dynamic characteristics of LD pumped Q-switched intracavity doubled Nd:YAG laser are studied theoretically.
