Time-resolved tomography of ultrafast laser-matter interaction

Opt Express. 2018 Feb 5;26(3):2873-2883. doi: 10.1364/OE.26.002873.

Abstract

We demonstrate time-resolved tomography with 200 fs resolution for the three-dimensional analysis of the non-linear dynamics of ultrafast laser-matter interaction inside the volume of transparent materials. We reconstruct as an example the three-dimensional spatial distribution of the transient extinction coefficient induced by focusing higher-order Bessel-Gaussian-beams into Gorilla glass. This approach can be employed to gaseous, liquid and transparent solid state matter which interact with laser light.
