Theory of Q-switched Nd: YAG Rate Equation Including Lower Level Relaxation
考虑激光下能级弛豫过程的调Q Nd∶YAG 速率方程理论分析

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.
