建立了适用于各种气压下(20×133—20×105Pa)的脉冲CO_2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CO_2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.
A six-temperature multi-frequency dynamic model for a pulsed CO 2 laser under various pressures (20 × 133-20 × 105Pa) is established. The model takes into account the overlapping effects of gain lines, the influence of sequence bands and the tropics, Lenze linear effect. Numerical simulation of the model can predict and explain the output characteristics of pulsed CO 2 lasers at different pressures, which can be used to evaluate different pumping designs and study tunable properties, providing theoretical support for the design of pulsed CO2 laser systems .
