【Abstract】 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.更多还原
