Paper Abstract

We present a prototype of a diffusion-cooled microwave excited CO2 laser. The microwave power, generated by a 2.45 GHz CW magnetron, excites the CO2:N2:He mixture in a discharge cavity. The magnetron is coupled to the cavity through a launching guide and two cascaded horns that match the TE10 guide mode to the cavity. The excess heat is mainly extracted by diffusive cooling to the cavity walls. We present measurements of the small signal gain and the output power as function of the gas pressure.
