本文利用一个简化模型,在推导出电子分布函数的基础上,给出了横流CO2激光器小信号增益沿气流方向分布的近似表达式,导出了小信号增益与顺流位置、气流速度、气压、顺流电极长度、放电电流之间的关系。理论与实验基本符合。

Based on the electron distribution function we derived approximately the analytic formula of the small signal gain along the gas flow, the dependence of the small signal gain on the downstream position gas velocity, mixture pressure, downstream length of the electrodes and the discharge current. The theory coincides essentially with the experiment.
