Abstract

A gas laser includes a housing tube and a capillary projecting therebeyond and having a Brewster window attached at a free end of the capillary. Laser power is increased without an increase in laser length by providing a mirror which terminates the housing in vacuum-tight fashion and is secured to the housing tube beyond an end of the capillary as an extension of the discharge channel of the capillary.
