Book Description
The chemical and energy transfer reactions involved in the helium-diluted DF-CO2 chemical transfer laser system are discussed. Experimental and theoretical rate coefficient literature is reviewed, and the most probable rates are selected for the kinetic model of the reaction system. Results of computer experiments show the relative importance of these reactions for pulsed laser simulation. Predicted laser performance is most sensitive to values of rate coefficients for DF-CO2 transfer, collisional deactivation of CO2(00 sup 0,1) by DF, and collisional deactivation of DF(v) by D and F.A detailed investigation of the relationship of cavity and chemical mechanisms for two levels of initiation is presented for an initial composition of XF:1F2:ID2:8CO2:40He at 50 torr and 300K with X = 0.1 and 0.01. For F = 0.01, a 260-microsec pulse with 6% chemical efficiency is predicted, while the higher level initiation level (F = 0.1) produces a 52-microsec pulse with 8% efficiency. (Author).

A Simple Model of a Line Selected, Long Chain, Pulsed DF-CO2 Chemical Transfer Laser

Languages : en
Pages : 43
Book Description
A rate equation model of a pulsed DF-CO2 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.
