Abstract
The simplified rotational relaxation time constant model of Hough, for pulsed chemical lasers, has been extended to CW diffusion chemical lasers to estimate the effect of rotational non-equilibrium on laser performance. The formulation was compared to experimental small signal gain, closed-cavity power, and spectral content. Effects of rotational relaxation rate on power extraction and spectral line distribution are predicted by numerical results of the present study. The dependence of rotational line shifting on mirror reflectivity has also been demonstrated.
