Paper Abstract

Low absorption coatings were examined using a high repetition rate copper vapor laser to study the surface temperature as a function of incident power. Nonlinear absorption was observed in some of the coatings as a result of increased incident power. A variety of commercial coating vendors using common dielectric oxide material combinations were surveyed. Wavelength, coating material, and coating vendor were varied to study their affects on the linearity of the absorption. The films were deposited by electron beam or ion beam sputtering technologies. Changes in the film characteristics were observed after exposure to high incident power. The nature of these changes and their permanency were also examined.
