A transverse radio frequency discharge excited carbon-dioxide slab laser has been operated with a hybrid waveguide/confocal resonator to produce an output power of 46 W. The active volume of 2.5 multiplied by 27 multiplied by 270 mm3 consists of a single discharge section with one cable feed. A spatial structure of radiation is presented.
