Mirror mount for lasers

摘要

A mirror mount for a resonator mirror of a gas laser which is cost-beneficial and simple to manufacture is composed of a tube of easily-workable material, for example steel, and a mirror receptacle that has a coefficient of thermal expansion matched to that of the mirror being supported in the receptacle. The mirror receptacle has a holding region that embraces the resonator mirror and has a spacer region that defines the minimum distance of the mirror from the end of the tube, whereby the mirror receptacle is deformable in a radial direction so that stresses caused by temperature fluctuations will not produce any damage to the mirror.
