摘　　要：研究了激光二极管侧面泵浦Nd:YAG声光调Q固体激光器中声光调Q重复频率对激光器斜效率的影响。通过实验发现在一定范围内存在最佳声光调Q重复频率,在这一频率下,斜效率在这一范围内取得极大值。实验所用激光器的最佳声光调Q重复频率为3kHz、泵浦功率为30W时,输出平均功率为4.40W,光-光转换效率为14.67%,斜效率为0.428。With laser diode side-pumped soild state laser, we research the influence of the repetition frequency of acousto-optics Q-switched to slope efficiency. Acordiing to experiment we find that there is a best repetition frequency within a certain range and then slope efficiency exist maximum value under the range. In the experiment, at the best repetiton frequency of 3kHz and the pump power of 30W, the output average power is 4.40W,the optical -optical conversion efficiency is 14. 67% and the maximum value of slope efficiency is 0.428.
