Evaporated Si films in combination with oxide materials such as SiO x form promising multilayer mirror coatings for chemical laser applications. However, high infrared absorption and relatively low damage threshold of theSi films presently limit the

A measurement technique is described where the absorption introduced by the addition of a single-layer thin film is separated into three parts: absorption (a) within the bulk of the film; (b) at the air-film interface; and (c) at the film-substrate i

In this time and wavelength regime optical coatings typically fail from thermal damage. Unlike catastrophic damage resulting from dielectric breakdown, one finds disparity among the thresholds for one or more of the following damage characteristics:

We previously reported on the deposition, absorption, and CO 2 -laser damage threshold for As 2 S 3 , As 2 Se 3 , and NaF coatings. It was shown that the damage threshold was much lower for coated than uncoated substrates and that the mechanism for d

Scanning electron microscopy (SEM) was used to identify four distinct laser damage mor-phologies in ZnSe/ThF4 multilayer mirrors. There were three types of defect-initiated damage morphologies. Oblong-shaped damage sites oriented perpendicular to the

Aluminum nitride/aluminum oxide multilayer protective antireflection coatings are being developed for use on laser windows. These materials have been shown to be relatively stable and scratch resistant, thus demonstrating their applicability for this
