Sub-micron elastic properties measurement of single laser-affected volume in fused silica

Yves Bellouard, Arunkrishnan Radhakrishnan

Non-ablative femtosecond laser exposure of transparent substrates leads to bulk volumetric changes, and consequently, localized structural changes resulting in micron-scale variation of elastic properties in the material. Here, we demonstrate the use of gr ...
