摘 要:
研究了LD泵浦Nd：YVO4／Cr^4＋：TAG调Q锁模激光器的输出特性，得到了如下结论：腔长较短时只能实现调Q脉冲激光输出，其峰值功率随泵浦功率成近似线性增加；当腔长增加到足够大时可实现稳定的被动词Q锁模激光脉冲输出。与调Q激光脉冲比较峰值功率得到很大提高；脉冲LD泵浦时，锁模脉冲激光输出平均功率减小，锁模脉冲峰值功率远大于连续泵浦锁模脉冲的峰值功率，谐振腔稳定区变宽．[著者文摘]

Abstract:
The output characteristic of passive Q-switched and mode-locked Nd：YVO4/and Cr^4＋：YAN solid-state lasers is studied by experiment,and the conclusion diode-pumped Nd： YVO4/and Cr^4＋：YAG laser can only realize the Q-switched laser output when the cavity long is shortened, the peak power will increase strightly with the pump power and realize the Q-switched mode-locking laser output. When cavity length has been in-creased enough, and the peak power will increase more than that with the Q-switched laser output. The average power of mode-locking laser will decline by pulsed pumped, but the peak power will rise more than the peak power by continuous. The stable area of cavity will become widened.[著者文摘]
