| 摘 要： | 从理论和实验的角度分析了在腔损耗调制状态下，当调制速度与CO2激光转动能级间的弛豫速度相当时，激光器输出脉冲峰值功率与增益系数间存在的非线性特性：峰值功率随增益系数的增加，存在饱和现象。这种特性是CO2 B-类激光器的特点，实验和理论模拟结果一致。

GainSaturation of Peak Power in Pulse CO2 Laser |
| |
| Abstract: | This paper analyzed the nonlinear relationship between the peak power of the output and the gain coefficient of the B-class CO2 laser with experimental and theoretic methods. The results show that when the modulating velocity nearly equals to the rate of transition between the rotation levels , the peak power of the output laser will be saturated at a gain coefficient point. This is the very specialize character of the B-class CO2 laser, the result of our experiment agreed with that of simulations well. |
