Description

<jats:title>Abstract</jats:title><jats:p>The nonlinear absorption coefficient of As<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub> 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 As<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub> glass by erasable and permanent photo-darkening is demonstrated using both holographic and direct multi-beam laser writing.</jats:p>
