A mathematical model of a CO_{2} 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.
