Abstract

A gas laser has a capillary which is supported inside a jacket tube by a resilient arrangement, which includes a spring washer having radially extending fingers extending from an annular portion having an axial aperture which is received on a cylindrical portion of a flange ring of the arrangement. The flange ring is soldered to the capillary tube with a glass solder in a manner which prevents the spring washer from coming in contact with the glass solder to change the properties of the spring washer.
