Paper Abstract

A new model describing initiating of laser-induced damage and ablation of transparent materials by femtosecond pulses is presented and discussed. The model is based on properties of shock electromagnetic wave (SEW) formed at laser fluences characteristic of femtosecond interactions with transparent media. It is presented simplified description of SEW-induced processes within approach of classical mechanics and electrodynamics: atoms are described as dipoles with certain ionization energy interacting with SEW in potential valley formed by crystal lattice. There are shown possibilities of laser-induced ionization, point-defect formation and delocalization of crystal points by SEW. Obtained results and predictions of presented theoretical model are compared with experimental results and shown to be capable of explaining many observed regulations and peculiarities of femtosecond laser interactions with transparent media.
