Abstract: A method and resulting laser tube apparatus constructed from a plurality of components adapted to be arranged in axial alignment and selfsupporting with respect to each other. The elements are adapted to withstand high baking temperatures and are provided at their mating surfaces with material capable of forming a flowable seal between the components during baking and subsequently solidifying to a hermetic seal upon cooling. End adjustment mirror mountings which combine adjustable functions together with desirable electrical properties are also disclosed, together with procedures for obtaining optical alignment of the resultant tube product.
