Paper Abstract

The relaxation of electronically excited oxygen in the active medium of chemical oxygen- iodine laser (COIL) may cause a nonequilibrium population of O2 and I2. Previously it has been the subject of theoretical study. The authors of this study suggest that the vibrationally excited oxygen molecules of O2(1(Delta) ,v) may take part in the I2 dissociation. In this work the vibrational population of O2 molecules in the COIL active medium was calculated. The O2 vibrational populations are obtained under the typical lasing conditions. The gaseous medium of COIL consists of O2, O2(1(Delta) ), I, I2, H2O, Ar. It is assumed that the chemical generator of singlet-delta oxygen is used. In this case the molecules of H2O play the important role in kinetics of the vibrationally excited oxygen molecules.
