Paper Abstract

A modeling scheme is presented for an iodine monofluoride chemical laser (IFCL) within the F-NH3-IF system which comprises 14 kinetic processes. The number densities of IF(B) and relevant excited species, and gain coefficients of the IF(B, v' equals 0, J' equals 21)yields(X, v' equals 5, J' equals 20) transition are obtained together with the influence of cavity pressure thereon by using Gear's auto-integration method on a PDP 11/73 Computer. Numerical calculation gives a small negative gain for a cavity pressure Pe < 4 Torr and a small positive gain for Pe > 6 Torr, respectively. It is predicted that Pe > 10 Torr would be necessary for lasing. The major energy transfer channels for IF(B) production are also analyzed.
