Paper Abstract

It is experimentally shown that more than 20% of O2 molecules in chemical oxygen iodine laser (COIL) active medium are vibrationally excited. Calculations show that approximately 4.5 vibrational quanta are formed under deactivating of one singlet oxygen O2(1Δ) molecule. Dependencies of threshold O2(1Δ) yield and gain on relative population of O2(1Δ,υ) are presented. The threshold O2(1Δ) yield increases with rising of the relative population of vibrationally excited oxygen and it can be some percents more than was considered before. The gain coefficient of COIL weakly depends on the degree of vibrational excitation of oxygen.
