Abstract
A damage resistant laser mirror is disclosed comprising a copper substrate highly polished to an optical finish coated with a thin layer of molybdenum or tungsten. The composite has good reflecting properties, is damage-tough, and conducts heat well away from the reflective coating. The superior adhesion of the coating is demonstrated by the fact that severe staining can be removed from the surface of the mirror by abrasive polishing without removing or damaging the coating.
