为了稳定脉冲光源,提出了一种基于光电导开光的设计思路.脉冲光源经过光分路器后,一大部分光经过适当长度的光纤延迟线接到普克尔盒光输入端,而小部分光通过误差调整电路,使普克尔盒两端的电压能够随前端光功率的大小而适当调节,最终输出稳定光源.

A novel design is proposed based on photoconductive switch for the stable pulse photosource. After the pulse photosource passing the optical shunting device, the most of light is transmitted to the optical input end of Pockels cell through the optical fiber delay line. The leavings is simultaneously converted to the error adjusting circuit to make the ends voltage of Pockels-cell change with the variety of optical power. Finally Pockels-cell outputs the stable photosource.
