Mirror for high powered laser - has copper mono-crystal surface with 100 or 111 orientation and etched structure

摘要

A high powered mirror, formed by the surface of a copper mono-crystal (DE3229697), includes a (100)- or (111)-orientation surface with an etched structure. The relecting surface has a curved shaped and pref. consists of a number of etched mono-crystal surfaces. The surface of the mono-crystal is pref. polished before etching takes place. Nitric acid is pref. used for the etching process. ADVANTAGE - The mirror is efficient and reliable and can accomodate higher power lasers.
