Abstract

Fused silica (a-SiO2) modified by high-intensity nanosecond and femtosecond laser pulses were studied by photoluminescence and Raman spectroscopy. The physical processes responsible for the defects formed during laser-induced material breakdown. For all laser irradiation conditions studied, laser-damaged a-SiO2 exhibited intense broad photoluminescence bands due to nonbridging oxygen hole centers, oxygen deficiency defects and other laser-induced defects.
