摘要
在三向侧面泵浦的二极管泵浦固体激光器(DPL)中声光Q开关结构确定的情况下,对声光Q开关在不同谐振腔以及同一谐振腔中不同位置时的调Q效果进行了一系列实验,发现脉宽最窄、峰值功率最高、调Q效率最大的位置正好在腔内振荡光的光腰附近.通过对该现象的分析,明确了振荡光对输出激光脉冲性能的影响规律,从而进一步分析DPL中泵浦光对调Q效果的影响,据此可以对声光调Q三向侧面泵浦DPL进行优化设计.
A series of experiments on the Q-switching result in different resonators and different locations in the multi-direction side-pumped DPL has been done. It can be seen from experimental results that the Q-switch location achieving the smallest pulse width, the biggest peak power and the largest Q-switching efficiency is exactly near the oscillating light waist. By discussing this phenomenon, we find the affecting pattern of the oscillating light on output pulse, and learn the influence of pump light on the Q-switching result further. The conclusion of this paper can be used in the optimal design of the acoustics-optical Q-switched multi-direction side-pumped DPL.
