Abstract

It is well-known that substrates and thin-film coatings for ultraviolet optical components are damaged by intense laser radiation, and widely believed that radiation-enhanced or even plasma chemistry in the laser environment exacerbates the damage problem. Unlike laser damage at infrared wavelengths, which is largely thermal, the damage morphology in UV optical materials exhibits both thermal and non-thermal characteristics. However, the fundamental physics leading to optical damage remains largely unexplored even in a qualitative way [1], despite the significant negative impact of low damage thresholds on laser systems cost, reliability and engineering.
