摘要
在实验上,以Cr4+ :YAG为可饱和吸收体,对Nd:YAG激光实现调Q锁模,得到平均脉宽为190ps的脉冲序列。利用被动锁模的涨落理论,分析了Cr4+ :YAG对Nd:YAG激光调Q锁模的动力学过程及各种影响因素,同时讨论了Nd:YAG的克尔透镜效应在调Q锁模过程中的作用,得到了与实验较为一致的结果。
Passive mode locking of a Nd:YAG laer have been realized with a Cr 4+ :YAG saturable absorber and 190 ps pulses are obtained.According to this result,eht dvelopment and critical factors of passive mode locking are analyzed by fluectuations theory.Meanwhile,the action of kerr lens effects of Nd:YAG is discussed.And the results basically agree with our experiment.
