Abstract

Achieving ultra-high laser resistance for high reflectivity coatings has become possible due to technological progress during the last years; keeping these performances up to their initial level over the storage or operation period seems a new challenge, as preliminary results reported last year in this conference showed a degradation of LIDT @ 1.06μm as a function of elapsed time and storage conditions. This work is clearly the continuation of last year's effort, as we report more observations on the same objects, with an emphasis on the use of surface-analysis techniques (TD-GCMS e.g.) to check potential correlation between degraded LIDT behavior and organic contamination.
