Laboratory of Galatea

The Laboratory of Galatea at EPFL focuses on exploring novel paradigms to locally tailor material properties using lasers. Their research revolves around understanding laser-matter interaction phenomena, developing new manufacturing processes based on 3D direct-write laser methods, and creating multi-scale systems from single monoliths. By utilizing ultrafast lasers, the lab can trigger non-linear absorption processes to modify transparent materials in three dimensions, embedding various functions like optical, mechanical, and fluid-handling capabilities in single monoliths. They investigate processes combining laser exposure with chemical etching steps, thermal laser reflow, and casting or molding with preformed cavities to push the boundaries of material modification.
