Abstract

We present numerical simulations of propagation of ultraviolet pulses through fused silica using a model that allows for the accumulative action of compaction back on the light. Compaction-induced self-focusing causes the light field to develop into a pattern of hot spots around the incident aperture that correlates with the damage patterns observed during marathon experiments designed to determine the onset of microchannel formation.
