Abstract

A gasdynamically cooled CO-laser with a dielectrically stabilized rf-discharge in the subsonic region is described, and laser performance data are presented. The laser is based on the well proven design realized several years ago in a 1-kW-laser at DLR Stuttgart. The dimensions have been scaled up to enable laser output powers up to 5 kW. The laser is run in a blow- down gas system which allows operation times of about 10 seconds. At present a maximum output power of 3.2 kW can be achieved.
