Abstract

Gold-coated copper mirrors with both diamond-turned and conventionally polished substrates have been evaluated in terms of their laser-induced damage thresholds (LIDT) at 10.6 μm. A detailed study of the surface finish on each component has revealed that a log-inverse log relationship exists between LIDT and substrate preparation.
