Simple Model of a Line Selected, Long Chain, Pulsed DF-CO(2) Chemical Transfer Laser

A rate equation model of a pulsed DF-CO(2) chemical transfer laser is Simplified by investigating the relationship of kinetic mechanisms. The model reduces to one equation which when Solved permits calculation of all pulse characteristics as a function of time. At low levels of initiation, predictions of this laser simulation model are in excellent agreement with those of a more comprehensive model presented in an earlier paper. Model predictions are also found to be consistent with experiment. The simplicity of the present model lends itself to easy physical interpretation and permits efficient and accurate prediction of transfer laser performance characteristics in regimes of practical interest.
