磁约束放电的CO激光激发系数

Excitation rates of CO laser with magnetically confined discharge

采用磁约束放电CO激光模型研究在外磁场作用下 :( 1)放电系统电子的能量分布变化 ;( 2 )电子对振动态CO分子的碰撞激发几率 ;( 3)CO分子振动 平动 ,振动 转动激发系数与磁场、温度的关系。研究表明 ,外磁场使原电场在电场方向上对电子作用变小 ,电子能量减小 ,并导致电子对CO分子的碰撞激发几率系数下降 ,而对V V ,V T激发系数影响不大。

A model of magnetically confined discharge CO laser is presented.Under the condition of magnetically confined discharge,the following factors are analyzed.First,the change of electron energy distribution of discharges system;secondly,the impact excitation rates of electron for the vibrating CO molecules;finally,the dependence of V-V,V-T rates on magnetic field and temperature.It is shown that with magnetic field added,the effect of electric field on electron decreases which decreases the impact excitation rate of electron for the vibration CO molecules in electric field direction and that the effect on V-V, V-T rates is weak.
