Laser Damage in Thin Film Optical Coatings
Abstract
This document has been prepared in the interest of aiding optical designers select laser damage resistant coatings for optical elements to be employed in military systems using lasers or encountering lasers used as weapons or countermeasures. It provides an extensive data base of damage thresholds for oxide, fluoride and chalcogenide single layer and multilayer coatings. The data base is supported by a detailed description of how the coatings were synthesized and how the measurements were performed to collect the damage threshold data. The basis from which the information was collected covers a period from 1984 through 1989. The material reviewed includes investigation of causes of damage in optical coatings and approaches to reducing or eliminating damage mechanisms with the objective of raising damage thresholds. The information should be found useful in selecting coating materials and techniques for their synthesis or as a tool in evaluating the susceptibility of existing coated optical elements.
