A new laser and mixing analysis 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 parallel mixing and constant lateral pressure with lasing due to single or multiple transitions between certain vibrationalrotational molecular energy levels. Excitation of the active medium traversing a Fabry-Perot optical cavity is caused by higly 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. Typical results are given for both uniform premixed and gradually mixing two-dimensional cavity flows. Volume I of this two-part final report documents the work accomplished on the development of the gain and power calculations, radiation model and its implementation into the constant lateral pressure Laser and Mixing Program LAMP.
