Bulk modification in transparent materials are usually classified as laser-induced damage that have been observed since the advent of powerful lasers. The results on laser-induced bulk modifications in transparent materials has been presented. The narrowed beam of an ultrashort laser pulse can break up into several filaments in the bulk material because of the counteracting self-defocusing by the free electrons, however, a single filament can even stabilize under certain conditions. This could establish the possibility of controlled and reproducible microstructuring of transparent materials even into the submicron region.
