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.
