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。
In experiments, a Q-switched mode-locked Nd: YAG laser with Cr4 +: YAG as a saturable absorber was used to obtain a pulse sequence with an average pulse width of 190 ps. Based on the fluctuation theory of passive mode-locking, the kinetic process and various influencing factors of Q-switched mode-locked Nd: YAG laser by Cr4 +: YAG were analyzed. The effects of Kerr lens effect of Nd: YAG on Q- In the role of the experiment has been more consistent results.
