Abstract

A gas laser housing having a housing and a metal cap attached thereto, includes a mirror mount attached to the metal cap. The mirror mount is provided with an annular region of reduced diameter affixed to the metal cap to absorb mechanical stresses and thereby prevents stress crack corrosion at the circumference of the housing tube.
