Based on a method presented in detail in a previous work by the authors, similar solutions have been obtained for the steady inviscid quasi-one-dimensional nonreacting flow in the supersonic nozzle of a CO/sub 2/--N/sub 2/ gasdynamic laser system, with either H/sub 2/O or He as the catalyst. It has been demonstrated how these solutions could be used to optimize the small-signal gain coefficient on a specified vibrational-rotational transition. Results presented for a wide range of mixture compositions include optimum values for the small-signal gain, area ratio, reservoir temperature, and a binary scaling parameter, which is the product of reservoir pressure and nozzle shape factor.
