Two different kinds of 1064 nm high-reflective (HR) coatings, with and without SiO2 protective layer, were prepared by
electron beam evaporation. Three-dimensional damage morphology, caused by a Nd:YAG pulsed laser, was investigated for
these HR coatings. Development of laser-induced damage on HR coatings was revealed by both temperature field calculation
and discrete meso-element simulation. Theoretical results met experimental very well.
