Abstract
Starting from the absorption of laser energy at a subsurface nanoparticle in fused silica, we simulate the consequent buildup of stresses and resulting mechanical material damage. The simulation indicates the formation of micropits with size comparable to a wavelength, similar to experimental observation. Possible mechanism for enhanced local light absorption are discussed.
