利用速率方程,对自调Q激光二极管抽运固体激光器进行了数值模拟。通过求解析解计算了自调Q脉冲的峰值功率、单脉冲能量、脉冲宽度、能量利用率、重复频率、平均输出功率等参量。根据自调Q二极管抽运固体激光器的特点,分别得到了使抽运阈值功率最小的最佳自调Q晶体长度和使光光效率最大的最佳自调Q晶体长度。

The behavior of self-Q-switched diode pumped solid-state laser (DPSSL) has been investigated by numerical simulation by using the rate equations of solid-state lasers. Analytical formulas for the peak power, pulse energy, pulse width, energy extraction efficiency, repetition rate and average output power are derived. The optimal length of self-Q-switch crystal with minimized threshold pump power and the optimal length with maximized light-light efficiency are obtained.
