摘　　要：对Nd:YAG全固体激光器Cr^(4+):YAG可饱和吸收调Q进行了实验研究。利用Cr^(4+):YAG被动调Q晶体,对1064nm基频激光脉冲的脉宽进行了压缩,并探索了泵浦电流与脉冲激光的关系。实验结果显示,得到了脉冲半高宽为6.63ns,重频参数为1.59×10~5Hz的1064nm脉冲激光。此外,随着泵浦电流的增加,脉宽逐渐减小,重频参数逐渐增加。The experimental study on Nd：YAG solid-state laser passively Q-switched by Cr4＋ ：YAG was carried out. In our case, the pulse width of 1064nm infrared laser pulse was compressed, further, the relationship between the pumping current and pulsed laser was studied. The results show that the laser output is obtained, which the pulse width is 6.63ns and the repetition rate is 1.59 × 10^5Hz. Moreover,the pulse width decreases and the repetition rate gradually increases with the pumping current increasing.
