摘　　要：本文对 CO激光器的稳态动力学模型作了修正和补充 ,通过计算机数值求解描述电子能量分布的Boltzmann方程和 CO分子动力学方程 ,得到了 CO分子电子基态中各个振动能级的粒子数分布 ,并首次计算出不同放电参数下泛频受激跃迁 (Δν=2 )的小信号增益系数。计算结果对泛频A modified CO laser kinetic model has been established for CO-overtone laser.By solving the Boltzmann equation for electronic energy distribution function and kinetic equation for CO laser plasma the vibrational population of CO molecules is numerically computed.The small signal gain coefficients of Δν=2 transition in different operation conditions have been calculated for the first time.The theoretical calculated results are useful for the design of CO-overtone lasers and optimizing of running parameters of the lasers.
