Abstract

Exposure of silica glass to focused femtosecond laser radiation produces a variety of structural modifications [1] that are accompanied by a localized change in volume [2,3]. This volume change can be used to apply displacements in a controlled manner, allowing the generation of intense, localized stress fields [4] whose magnitude, orientation, and shape are easily manipulated through tuning of the writing parameters [4-6].
