Abstract
Irradiation of the As2S3 chalcogenide glass by a train of focused femtoseco nd laser pulses from a master oscillator based on a Ti:sapphire crystal res ults in the formation of submicron structures in the bulk of the sample wit h modified optical properties. The minimum exposure time for producing such microstructures does not exceed 1 mus. A model based on two-photon absorpt ion of laser radiation and local beating of the sample material is proposed for this phenomenon.
