Abstract

A gas laser tube assembly includes: PA1 a gas laser tube having two ends; and PA1 two optical elements each vacuum-tightly closing off a respective one of the ends of the gas laser tube, at least one of the optical elements at one end of the gas laser tube including a flange and a terminating body formed of a given material; PA0 the flange: PA1 being rigid, being formed of a metal thermally matched to the given material of the terminating body, being inserted into and connected to the gas laser tube, having the shape of a washer with two sides and a central beam passage opening formed therein, and having a meandering profile with a plurality of right angle turns immediately following each other and pointing alternatingly toward one of the sides of the flange; and PA0 the terminating body: PA1 being formed of a material transparent to laser radiation, having the shape of a plate, being inserted into the beam passage opening, being connected to the flange by glass solder, and being extended beyond the tangential plane of both of the sides of the flange in a direction normal to the plate and a method for manufacturing the same.
