Abstract

A polished high-intensity reflector of copper, silver or gold for laser applications. In contrast to known mirrors of electrolytic copper whose surface is permeated with grain interfaces, this new mirror is constituted by the surface of single crystals. This surface may be polished. Alternatively this surface may be formed by copper single crystals etched in the (100)- or (111)-orientation planes. In the latter case crystallites making up the surface contain etching pits each of which form small spherical mirrors of their own. Mirrors with etched surface withstand higher laser energies than mirrors with polished surface. As a shield protecting against laser beams several single crystal mirrors may be combined in arrays. The reflecting surface may be either flat or curved.
