| 摘 要： | 建立了适用于各种气压下(20×133—20×105 Pa)的脉冲CO2激光器的六温度多频动力学模型，该模型考虑了增益谱线重叠效应，序列带、热带的影响，以及非洛伦兹线型效应.对模型进行数值求解可以预言和解释不同气压下的脉冲CO2激光器的输出特性，有助于评价不同的抽运设计和研究可调谐特性，为设计脉冲CO2激光系统提供理论支持.

| Abstract: | A six-temperature multifrequency dynamical model of pulsed CO2 lasers is presented, taking account of the collision-dependent overlap of rotational lines, the effect of hot bands and sequence bands on the gain spectrum, and non-Lorentzian line overlap effect in a wide range of pressures from 20 torr to 20 atm. Theoretical calculations of pulse shape and laser spectrum have good agreement with experimental results. This model should be useful in the understanding of pulsed CO2 laser dynamics, in the evaluation of alternative pump schemes, and in the investigation of tunable characteristics. Thus it can provide theoretical support for the design of pulsed CO2 lasers. |
