本文对Cr4+:YAG 被动调Q Nd:YAG 陶瓷激光器的输出特性进行了理论和实验研究。在相同泵浦功率和不同输出耦合透过率条件下,实验测量了被动调Q 陶瓷激光器的输出激光重复频率、平均输出功率以及单脉冲能量,并与理论计算结果进行了比较。研究结果表明,随着输出耦合透过率的增加,输出激光重复频率单调减小,而平均输出功率及单脉冲能量则呈现出先增加后减小的变化趋势,只是平均输出功率及单脉冲能量所对应的最佳输出耦合透过率会有所不同。

The output properties of passively Q-switched Nd:YAG/Cr4+:YAG ceramic laser was studied theoretically and experimentally. The repetition rate, the average output power and the single pulse energy were measured for different output coupling transmissions. The experimental results were compared with the theoretical calculation results. It can be shown that the repetition rate of output Q-switched laser decreases with the increasing of the output coupling transmission, whereas the average output power and the single pulse energy firstly increase to maximum and then decrease as the output coupling transmission increases. However, the optimal output coupling transmissions for the maximum average output power and the maximum single-pulse energy are different.
