ABSTRACT:
Two central bore assemblies are constructed, each including a ceramic tube having a plurality of drilled disc assemblies frictionally attached thereon. A cathode element is inserted in the central portion of an outer envelope, as are the two grid-bore assemblies. The inner portion of the envelope is maintained in a partial vacuum, and heat is applied to the exterior, thereby shrinking the envelope over the grid-bore assemblies. A taut tungsten wire is inserted through the bore, and the envelope in the region of each of the disc assemblies is heated successively, from one side to the other. This achieves precise alignment of the central bore throughout the laser. Anode elements are inserted at either end, and mirrors are attached. After preliminary adjustment, the mirrors are fine-tuned by means of application of a narrow band of heat on the mirror neck, as slight transverse forces are applied to the sides of the mirrors.
