Abstract
An all metal, microwave-pumped, waveguide CO.sub.2 laser includes a waveguide providing a vacuum envelope containing the CO.sub.2 gas having a longitudinal ridge extending at least partially across the width of the waveguide and extending along a length of the waveguide and a ceiling facing the ridge. The ridge and ceiling have horizontal surfaces facing one another which together function as an optical waveguide of the laser and define a longitudinal optically active region therebetween which, in the preferred embodiment, opens out into remaining portions of the waveguide along either side of said ridge. A pair of reflecting mirrors are located at each end of said optically active region and an antenna or ramped waveguide couples a microwave source into the waveguide.
