Abstract
Laser nanostructuring of glasses has attracted particular attention during laser decades due to its numerous applications in optics, telecommunications, sensing, nanofluidics, as well as in the development of nanocomposite materials. Despite a significant progress achieved in this field with the development and use of femtosecond laser systems, many questions remain puzzling. This study is focused on the numerical modeling of ultrashort laser interactions with glasses. Firstly, we consider laser light propagation and nonlinear ionization. Then, nanocavitation processes in glasses are modeled, followed by the hydrodynamic evolution of pores and cavities. The required conditions for nanopore formation and volume nanogratings erasure in the typical femtosecond laser-irradiation regimes are discussed in the frame of the developed model.
