Abstract

The output laser power of a small-scale subsonic Chemical Oxygen-Iodine Laser has been improved from 5 to 34 watts with the same gas pumping system. To obtain a good agreement between the model and the experiments we have introduced the temperature effects on the reaction kinetics. We show also that the addition of a buffer gas such as SF₆ achieves a significant cooling of the active medium, which in turn allows a better laser power extraction.
