Title: ANTIREFCTIVE SURFACE STRUCTURES ON OPTICAL ELEMENTS
Abstract:
The invention relates to methods for fabricating an antireflective surface structure (ARSS) on a Ⅱ-Ⅵ optic including providing an optical element comprising a Ⅱ-Ⅵ material having an absorption edge; and exposing at least one surface of the optical element to a laser beam having a wavelength from below the absorption edge of the Ⅱ-Ⅵ material to a maximum wavelength within the absorption edge of the Ⅱ-Ⅵ material, wherein ARSS are formed on the at least one surface of the optical element.
