Laboratory

Summary

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.

Yves Bellouard

Dr. Yves Bellouard is Associate Professor in Microengineering at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, where he heads the Galatea lab and the Richemont Chair in micromanufacturing. He received a BS in Theoretical Physics and a MS in Applied Physics from Université Pierre et Marie Curie in Paris, France in 1994-1995 and a PhD in Microengineering from Ecole Polytechnique Fédérale de Lausanne (EPFL) in Lausanne, Switzerland in 2000. For his PhD work, he received the Omega Scientific prize (2001) for outstanding contribution in the field of microengineering for his work on Shape Memory Alloys. Before joining EPFL in 2015, he was Associate Professor at Eindhoven University of Technologies (TU/e) in the Netherlands and prior to that, Research Scientist at Rensselaer Polytechnic Institute (RPI) in Troy, New York for about four years where he started working on femtosecond laser processing of glass materials. From 2010 until 2013, Yves Bellouard initiated and coordinated the Femtoprint project, a European research initiative aiming at investigating a table-top printer for microsystems ('3D printing of microsystems'). In 2013, he received a prestigious ERC Starting Grant (Consolidator-2012) from the European Research Council and a JSPS Fellowship from the Japan Society for the Promotion of Science. His current research interests are on new paradigms for system integration at the microscale and in particular laser-based methods to tailor material properties for achieving higher level of integration in microsystems, like for instance integrating optics, mechanics and fluidics in a single monolith. These approaches open new opportunities for direct-write methods of microsystems (3D printing). Personal website
