ABSTRACT
In order to understand the damage mechanisms inside the optics of the high power laser facilities, a model sample has been prepared by introducing gold nanoparticles into a silica film. The mean diameter of the gold clusters is 2.5 nm. Different parts of the sample were irradiated at wavelength 355 nm and fluences up to 1 J/cm2. By looking with x-ray photoelectron spectroscopy at the intensity of the Au 4f peak relative to that of the Si 2p peak, a surface Au density enrichment is observed. We interpret this as indicating that the gold atoms migrate toward the surface upon the laser irradiation.
