Abstract
We report the densification of fused silica as a function of exposure to pulsed 193-nm excimer-laser irradiation. Defining a dose as the number of pulses N times the square of fluence I per pulse, we find that densification follows a universal function of dose, a × (NI2)b, where a and b can vary somewhat according to glass preparation. Densification is measured with interferometry and birefringence, interpreted with a finiteelement elastic model. Wave-front distortion for a typical photolithographic lens element in typical use conditions is described.
