摘要

A new laser and mixing computer program is described which considers the coupling between gasdynamic properties,cavity characteristics,and resulting laser radiation for diffusion-type chemical laser oscillator cavities. The formulation assumes non-uniform mixing with lateral pressure gradients and lasing due to a single transition between the upper and lower laser levels. Excitation of the active medium traversing a Fabry-Perot optical cavity is caused by highly exothermic reactions between gradually mixing reactants discharged from a grid nozzle. Uniform,premixed inviscid laser cavity flows can be investigated as a special case of the more general analysis. (Author)
