Chemical Laser Analysis Development. Volume I. Laser and Mixing Program Theory and User's Guide.

摘要

A new Laser And Mixing Program (LAMP) 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 vibrational/rotational molecular energy 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. The report contains a description of the analysis as well as a user's manual. (Author)
