ABSTRACT:
Gas laser discharge tube with copper halide vapors. The tube has a vacuum tight quartz casing equipped with at least two electrodes which are disposed in extensions of the quartz casing. The electrodes are made of copper particles of irregular form which make contact with the vacuum tight terminals. The copper particles are piled in quartz tubes disposed coaxially in the quartz extensions, so that between the quartz tube and the extensions of each electrode there is formed a cavity. Each quartz tube is perforated along its entire surface and it is plugged by a perforated copper plate through which the vacuum tight terminal passes. The apertures in the quartz tube and in the copper plate have a smaller diameter than the diameter of the copper particles. This gas discharge tube may be used in scientific research, laser locating, and the like.
