Abstract

The problem of relaxing mixture flow in a carbon dioxide gasdynamic laser is solved. Infrared radiation-power density generated is calculated for gas pressures at the nozzle input of 25 and 100 atm. An increase in power with increase in initial pressure is observed for suitable selection of mixture composition and initial temperature.
