长下降沿时间的KD*P泡克耳斯盒驱动电源对全固态腔倒空激光器输出特性的影响

设计了一种脉冲激光二极管抽运的低重复频率全固态腔倒空激光器，为了尽可能减小损耗的影响，在腔内采用双薄膜偏振片结构，使反射率较高的垂直方向线偏振光在腔内振荡。以此装置为基础，就泡克耳斯盒驱动电源较长的下降沿时间对全固态腔倒空激光器输出特性的影响进行了实验研究。结果表明当泡克耳斯盒驱动电源的下降沿时间远大于腔内的一次往返时间时，激光器输出特性会发生明显地变化：增大电流强度会导致脉冲宽度增大，脉冲能量经历先增大后减少的过程；增大泡克耳斯盒驱动电源的开门时间，也会导致脉冲宽度和能量发生类似的变化。

Abstract

A low-repetition-rate pulsed LD-pumped cavity-dumped solid-state lasers are designed, in order to minimize the influence of losses, two thin film polarizer are used in the cavity, so that the higher reflectivity of vertical vibration of linearly polarized light is retained in the cavity. Based on this device, The influence of the longer fall time of Pockels cell driving power influence on solid-state cavity-dumped lasers has been studied experimentally. The results show that when the fall time of Pockels cell driving power is longer than a round-trip time in the cavity, some significant changes will occur in the output characteristics of the laser, with the increase of current intensity, the pulse width will increase, and the pulse energy increases first and then decreases; with the increase of the gating time of Pockels cell power, some similar changes will occur on the pulse width and the pulse energy.
