Abstract

The invention concerns a coaxial glass gas laser tube, consisting of a capillary tube connecting at its inner open end with a surrounding cylindrical space bounded by an outer tube enclosing the capillary tube, an end wall located at some distance from the inner end of the capillary tube, and a termination opposite the latter, which joins the capillary tube to the outer tube; one optical element is located on the end of the capillary tube extending past the end of the outer tube, and the other on the end wall.
