abstract

In the past decades, efforts have been concentrated on reaching more laser resistant multilayers optical components in the Infrared (IR) range. New designs and materials have been investigated and among them binary or ternary oxide mixtures have revealed to be very profitable to improve the laser damage resistance of the coatings in the IR. The physical characteristics of such mixed materials are indeed tunable and the deposition process associated allows to obtain multilayers with smoother interfaces, which reduces considerably the damage threshold of the component. The present work is focused on the study of pure materials and their binary oxide mixtures in the UV range, using S-on-1 testing, for two different laser beam sizes. Samples resistance to multipulse irradiation is then compared for both beam sizes, extracting the data with a thermal model assuming nanometric inclusions. The fatigue effects of the set of sample have also been investigated, showing no clear trend of fatigue for all tested components.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
