Abstract
The invention is concerned with novel pre-stressing of a reflecting surface such as a mirror, that is to be irradiated by a high energy laser beam or similar source, in such a manner that the beam-induced heating of the reflective surface causes a relaxation of the pre-stress that is designed to produce a surface distortion substantially equal and opposite to that caused by the heating.
