Abstract

The laser damage thresholds (LDT) of optical coatings lie, as a rule, markedly below those of the respective bulk materials. This is due to diverse specific real-structure properties which depend in a highly complex and sensitive way on deposition conditions. With evaporated or sputtered coatings as an example, some correlations between structural thin film properties and the LDT are discussed with concern to a further increase of the damage resistance.
