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.
