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.
