Mid-infrared femtosecond laser-induced damages in As2S3 and As2Se3 chalcogenide glasses

Abstract In this paper, we report the first measurements of mid-infrared (MIR) femtosecond laser-induced damage in two typical chalcogenide glasses, As2S3 and As2Se3. Damage mechanism is studied via optical microscopy, scanning electron microscopy and elemental analysis. By irradiating at 3, 4 and 5...
