Picosecond laser microfabrication of infrared antireflective functional surface on As2Se3glass
摘要
Abstract
Chalcogenide glasses are formed of chalcogen of S, Se, Te with doping of a certain of other metal elements. Due to the lower refractive index, temperature coefficient and good infrared transmittance, it has been recognized as the ideal materials for a new generation temperature non-refrigerated infrared optical system. In order to decrease the large reflection losses, researches on multi-layer thin-film coatings for anti-reflection (AR) with good performance were performed. However, disadvantages of the method are needed to be overcome, such as high costs and short lifetimes. Recently, surface micro-structures have been shown to be a good alternative potential to multi-layer thin-film AR coatings in many infrared and visible-band applications.
