摘要
本文比较了考虑与不考虑激光下能级弛豫过程的两种形式的调Q速率方程,并以二极管激光侧面泵浦电光调QNd∶YAG为例,分别采用两种形式的调Q速率方程,分析了调Q过程中上、下能级粒子数变化过程,计算了输出调Q激光脉冲波形、峰值功率以及能量,进行了比较分析,并解释了调Q“子脉冲”
Two kinds of Q-switched rate equation including and non-including lower level relaxation are analyzed. As an example, diode side-pumped (Q-switched Nd:YAG laser is studied using the two kinds of rate equation. The variations of upper and lower level population are given, (Q-switched pulse waveform, peak power and pulse energy are calculated. In addition, sub-pulse and tail phenomena are also explained.
