Abstract

An analytical method is developed, which enables die use of dependencies of die gain and temperature in the resonator of the supersonic chemical oxygen-iodine laser (COIL) on the iodine flow rate, for calculation of the iodine dissociation fraction F and the number N of O₂(¹Δ) molecules lost in the region of iodine dissociation per I₂ molecule. The method is applied to supersonic COILs with transonic injection of iodine and different types of supersonic nozzles. It is found that F is a nonmonotonous function of the iodine flow rate. The maximum value of F is 0.55 for our grid nozzle and 0.94 for our slit nozzle.
