title = "Sub-bandgap femtosecond laser processing of chalcogenide thin films: Incubation and damage thresholds",
abstract = "Chalcogenide glasses are promising for integrated photonics due to their strong optical nonlinearity and mid-infrared transparency. We investigate the response of As2S3 and As2Se3 thin films to sub-bandgap femtosecond irradiation at 1200 nm, determining the single- and multipulse damage-threshold fluences and the incubation factor. Structural modifications and photocrystallization were analyzed via SEM, AFM, and Raman spectroscopy. The low incubation factor reveals increased sensitivity with pulse accumulation, providing insights into nonlinear light-matter interactions in chalcogenide films at telecom wavelengths.",
