R&D: Ultrafast Laser Nanostructuring in Transparent Materials for Neam Shaping and Storage

Optical Materials Express has published an article written by Yuhao Lei, Huijun Wang, Gholamreza Shayeganrad, and Peter G. Kazansky, Optoelectronics Research Centre, University of Southampton, Southampton, SO17 1BJ, United Kingdom.

Abstract: “We review recent progress in femtosecond laser anisotropic nanostructuring of transparent materials, including silica glass and thin films. With different writing parameters, oblate nanopores, single lamella-like structures and nanoripples are demonstrated, which can be used in geometric phase optical elements, space variant polarization converters and multiplexed optical data storage.“
