Local heating of chalcogenide glass sample by a train of high-intensity femtosecond laser pulses depending on non-linear and thermal properties of the glass is studied in a theoretical model and in experiments on photo-induced glass modification.
Chalcogenide glasses are novel highly non-linear materials for photonics. Modification of optical glasses by high-intensity femtosecond pulses is a novel fast developing technology based on non-linear effects. In this paper, the advantages of using the method of femtosecond modifications for the fabrication of highly non-linear 3D photonic structures in bulk chalcogenide glasses are overviewed. Design...
