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 linked up to the cavity through a launching guide and two cascaded horns that couple the microwave power to the cavity. The excess heat is mainly extracted by diffusive cooling to the cavity walls. Measurements of the small signal gain and the output power as function of the gas pressure are shown.
