Abstract

A gas laser operating at room temperature, consisting of a cylindriform sealed tube (1) with two electrodes (3) of gold or a gilt material and filled with nitrogen with a partial pressure at room temperature of 0.1-2.0 torr, xenon with a partial pressure of 1.0-3.0 torr, carbon monoxide with a partial pressure of 1.0- 3.5 torr, helium with a partial pressure of 15-30 torr and possibly oxygen with a partial pressure of not more than 60 mtorr. The laser tube may be equipped with a hollow metal mirror (5) provided with a 100% reflecting gold coating and a flat mirror (6) being a partially transparent window, Further it may contain a zeolite (8).
