Abstract

A flame sheet model is presented which describes continuous wave (cw) HF/DF chemical laser performance and includes the effects of translational and rotational nonequilibrium. The model is then simplified by the realistic assumption that translational and rotational relaxation rates are fast compared with convection, chemical pumping, and collisional deactivation rates. It is also assumed that the homogeneous width Δvh is small compared with the Doppler width Δvd. The resultant system of equations is independent of rotational relaxation. Amplifier and oscillator solutions are discussed. It is concluded that a reasonable first estimate for cw HF/DF chemical laser performance can be obtained by assuming rotational equilibrium and translational nonequilibrium.
