Power performance predicting for continuous-wave oxygen-iodine laser with different pumping types

The two-level generation model taking into account kinetic and optical losses has been applied to predict power performance of a continuous-wave oxygen-iodine laser (cw OIL) with chemical, electric discharge, and optical pumping. The cw OIL operating modes mapping method using similarity criteria, which allows to classify them vividly according to the power efficiency level, has been modified. A method for simplified estimation of the peak power efficiency of cw OILs with different pumping types has been developed. A comparative analysis of the power efficiency calculation results by using both methods and the experimental data has shown their applicability in practically important cases when low losses are ensured.
