Femtosecond Laser Structuring of As2S3 Glass for Erasable and Permanent Optical Memory
Published online by Cambridge University Press: 01 February 2011
Abstract
The nonlinear absorption coefficient of As2S3 glass has been measured to be 2.0 cm/GW for femtosecond pulses at 800 nm. Femtosecond laser structuring via two photon absorption in bulk As2S3 glass by erasable and permanent photo-darkening is demonstrated using both holographic and direct multi-beam laser writing.
