Abstract

The efficient power operation in a chemical oxygen-iodine laser for subsonic modes has been demonstrated. It is shown that the substitution of the buffer gas N₂ by CO₂ does not cause any significant variation in the dependence of the output power on the degree ofdilution ofthe active medium. The maximum power was 581 W for the flow rate of molecular chlorine 22 mmole/s that corresponds to a chemical efficiency of &eegr;_chem = 29%.
