Nettleton, J E; Barr, D N; Fox, C S

A gas filled laser tube for use in a Fabry-Perot cavity to generate electromagnetic radiation (EMR) within a given band of submillimeter wavelengths is described comprising: an elongated tube of dielectric material characterized by low loss propogation of radio frequency EMR; a pair of end caps hermetically sealing the ends of the tube, the caps being transparent to the given band of EMR; and a transmission line formed by twin parallel wires for high frequency EMR spiralled around the exterior surface of the tube such that the maximum intensity electric field line between the wires which penetrates the tube is parallel to the tube axis.
