Henderson, A R

A multiple cavity waveguide laser is described comprising first and second blocks of dielectric material having mutually contiguous faces sealed to one another, first and second pairs of side by side waveguide grooves formed in the first and second blocks, respectively, each groove opening to a respective one of the faces, first relatively thin partition means extending along and separating the grooves of each of the pairs of waveguide grooves from one another and forming a first side of each of the grooves, second relatively thin partition means extending along and interposed between the first and second blocks and separating the grooves of the first pair from the grooves of the second pair and forming a second side of each of the waveguide grooves, reflective means mounted at opposite ends of the grooves, the grooves, the partition means, and the reflective means defining a plurality of resonant cavities, a lasing medium in the cavities, one of the partition means being electrically conductive and forming a first electrode extending along one of the first and second sides of each of the grooves, and means for coupling radio frequency electrical energy between the first electrode and a side of each of the waveguide grooves opposite the first electrode.
