摘　　要：分析了同时锁模／调ＱＮｄ：ＹＡＧ激光的形成过程。采用预激光技术实现了锁模／调Ｑ同时运转。讨论了影响预激光的因素。为获得无次结构、变换极限的超短脉冲，预激光时间应大于１～１．５ｍｓ．获得了有调Ｑ包络的超短脉冲，峰值功率为１０５Ｗ，比单独锁模时提高１０３倍。The pulse evolution of a simultaneous mode-locked and Q-swiching Nd:YAG laser isdiscussed with the prelaser technique,In order to obtain a train of steady-state and trans-form-limited ultra short pulses,a prelaser period longer than 1～1. 5 ms must be selected.Apulse peak power of 105 W has resulted with such a system,which is 103 times as great asthat obtained with a system with only a mode-locked laser.
