Theoretic Investigation of Phase Mismatch in a High Power all Solid-state Q-switched Intracavity Frequency Doubled Laser

给出了在考虑相位失配情况下高功率全固态内腔倍频调Q激光器的速率方程解的情况。以Nd:YAG声光调Q内腔倍频激光器为例,建立并数值求解相位失配条件下的速率方程组,从理论上分析了相位失配和泵浦功率等参数对内腔倍频调Q激光器输出功率、脉冲宽度等的影响。

The solutions of rate equations in a high power all solid-state Q-switched intracavity frequency doubled laser by taking the phase mismatch into account are presented. By taking acousto-optical Q-switched intracavity frequency doubled Nd：YAG laser for example, rate equations under phase mismatch were described and solved numerically. The influence of phase mismatch and pump power on output power, pulse width in Q-switched intracavity frequency doubled laser were analyzed theoretically.
