The direct laser writing micro relief structures on chalcogenide glass by laser beam recorder of master discs

Abstract

The area of the direct laser writing application is much wider than only recording of optical discs The direct laser writing in photoresist enables to be fabricate a wide range of continuous micro relief phase elements .Recording systems with precise rotating devices, positioning of optical heads, and stabilizing of the power of recording lasers allow the creation of various devices for writing micro-optical elements.
