摘　　要：利用Siegman速率方程组,采用自适应变步长龙格-库塔数值方法,对Cr4+∶Nd3+∶YAG自调Q陶瓷激光器的输出特性进行了数值模拟,详细讨论了Nd3+∶YAG陶瓷厚度以及Cr4+离子浓度对陶瓷激光器的重复频率、峰值功率、单脉冲能量、脉冲宽度、以及平均输出功率等输出特性的影响。研究结果表明,随着参与作用的Nd3+离子数的增加,输出激光脉冲重复频率和平均输出功率均会明显提高;随着Cr4+离子浓度的升高,输出激光脉冲重复频率和平均输出功率则会明显下降。Based on Siegman rate equations, the output properties of Cr4＋：Nd3＋：YAG self-Q-switched ceramic laser are numerically analyzed with the method of self-doped RungeKutta. The effects of the thickness of ceramic Nd^3＋ ： YAG and the concentration of Cr^4＋ in the ceramic Cr^4＋ ： YAG on the output properties of the ceramic laser, such as repeatitive frequency, the peak power, the energy of a single pulse, the pulse width, as well as the average output-power are discussed in detail. The results show that the repeatitive frequency and the average output-power of the ceramic laser increase with the increasing of the concentration of Nd^3＋ , and decrease with the increasing of the concentration of Cr^4＋,
