3D Microfabrication in YAG Crystals by Direct Laser Writing and Chemical Etching

Not Accessible

Your library or personal account may give you access

Abstract

We report selective etching of mm-length direct laser written three-dimensional microstructures inside Nd:YAG crystals. The structures exhibit enhanced etching selectivity compared to unmodified YAG. Origin of this selectivity is investigated using Nd3+ micro-spectroscopy and micro-Raman.
