NUMERICAL MODELING OF A GAS-DISCHARGE CO2 LASER WITH DIFFUSION COOLING
R. S. Galeev and A. A. Fedosov UDC 533.9.03:537.5 A mathematical model of a CO2 laser with diffusion cooling is proposed that is based on the simultaneous solution of glow-discharge equations in a quasilinear approximation with account for ambipolar diffusion, energy equations, and vibrational relaxation of the radiating gas. Consideration is given to a steady glow discharge in a cylindrical tube for the case of an electronegative gas. The model of a plane-parallel resonator is used on the assumption of constant radiation intensity inside the resonator. The developed model differs from the known ones by allowance for negative ions.
