Nanogratings and nanoholes fabricated by direct femtosecond laser writing in chalcogenide glasses
journal contribution
posted on 2024-07-11, 07:03 authored by Qiming Zhang, Han Lin, Baohua Jia, Lei Xu, Min GuWe report on the fabrication of sub-wavelength nanostructures on the surface of As2S3 chalcogenide glasses by appropriately controlling the irradiation condition of single-beam direct femtosecond laser writing. Nanogratings with a period of 180 nm were realized by multipulse irradiation. More importantly controllable nanoholes as small as 200 nm in diameter (one quarter of the illumination wavelength) were, for the first time, achieved in As2S3 using direct laser writing by single-pulse irradiation.
