Simplified Model of a CW Diffusion-Type Chemical Laser - An Extension.
Abstract
The simplified two-vibrational-level model of a cw diffusion-type chemical laser presented by Mirels, Hofland, and King is extended to include multiple vibrational levels. Both laminar and turbulent diffusion are considered. Expressions for axial gain distribution and net output power from a Fabry-Perot optical resonator are deduced. For a given lasing species, the resulting cw chemical laser scaling laws are the same as those previously deduced by Mirels, Hofland, and King, except for the dependence of certain coefficients on rotational quantum number J and temperature T. Broadwell previously presented a multiple-vibrational-level model for a cw chemical laser that was limited, however, to turbulent diffusion. The flame-sheet-mixing model used in the present study is shown to give results that are identical with those from the scheduled-mixing model of Broadwell when mean chemical rates are used. (Author)
