A method of adjusting an optical element of a gas discharge laser, which element is provided at one end of a tubular metal support with the support in turn secured to the laser tube, by drawing a tubular section of the support beyond the yield point of the metal of which the tubular section consists during or after adjustment of the optical element by deformation of the tubular section throughout the circumference. An accurate adjustment of the element thereby takes place in a simple manner in which no stresses remain in the material which might otherwise maladjust the laser. The tubular section preferably consists of copper or nickel. |
