In this paper, investigations have been made on a CO2 laser with revolving flow and circular metal cavity. A theoretical model for calculating the stable operation parameter of the new laser is presented. Calculation on small signal gain under many operation conditions has been made. The optimal operation conditions are achieved. A stable discharge with the input power density of 23 W/cm3 had been obtained in the experiment.
