A new type of waveguide laser is described in which a single-surface concave metal waveguide also doubles as the grounded electrode in a radio-frequency-excited gaseous discharge. The laser's output modes and spectrum have been studied theoretically and experimentally for cw CO/sub 2/ operation of the laser. Overall operating efficiency and mode stability are comparable with those of conventional dielectric waveguide CO/sub 2/ lasers, and advantages of the metal waveguide laser include convection cooling, intracavity mode control, and partial self-alignment.
