建立了磁约束放电CO激光的模型 .在该模型下分析、计算了CO气体放电系统电子的能量分布函数 ;CO分子的电子碰撞激发概率以及CO分子的振动 振动 (V V) ,振动 平动 (V T)激发概率 ;CO分子各振动态的布居数分布和对应的小信号激光增益系数 .研究表明 ,由于磁场的加入CO分子振动态布居数分布出现凹陷 .在该区域获得了更大激光的小信号增益 The model of magnetic confinement discharge (CO) laser was established. Under this model, the energy distribution function of electrons in CO gas discharge system was calculated and analyzed. The probability of electron collision excitation of CO molecule and the vibrational vibration (VV) ) Probability of excitation, population distribution of CO molecules in each vibration state, and corresponding small-signal laser gain coefficient.The results show that there is a depression in the population distribution of the CO molecule vibrational state due to the addition of a magnetic field, and a larger laser Small signal gain
