Abstract

A CO.sub.2 laser wave guide, which is excitable by a high frequency signal, as two boron nitride bodies (11a, 11b; 111a, 111b) which are held in position in a housing (10) by a specially shaped spring (14, 114) which presses the boron nitride bodies against the inner surface (10a) of the housing for good heat transfer and dissipation. A spacer (18) holds the boron nitride bodies apart to provide a gap (15) in which one electrode is held. The specially shaped spring operates, in addition to holding the boron nitride bodies in place, as the opposite electrode. This structure requires few parts and these parts do not have to meet high tolerance requirements, nor is it necessary to provide a high surface finish for the individual components.
