报告摘要:
Ever since the discovery of laser in 1960, it became evident that laser was a “solution looking for a problem”. A huge number of applications emerged throughout the years in the field of material engineering. More recently, and with the discovery of ultrafast laser sources, the applications palette has been extended and the reason for this is that these sources offer unique processing quality in almost any material, from metals to polymers but also in glass and ceramics. At the Lasers, Plasmas and Photonic Processes (LP3) laboratory we focus on laser-matter interaction in short and ultrashort temporal regimes. Studies address fundamental mechanisms induced when a pulsed-laser beam interacts with matter, in order to understand the physical phenomena that control the effects of the interaction and then to develop innovative photonic processes. The latter target new diagnostics and means of analysis (LIBS, sub-picosecond X-ray imaging, time-resolved X-ray diffraction), the generation of new material (high purity nanoparticles) or materials with new properties (surface structuring) and at last the development of new manufacturing processes (subtractive and additive micro/nano technologies). An overview of these activities will be given during this seminar.
报告人介绍:
Dr. Alexandros Mouskeftaras is a Tenured Researcher at the French National Centre for Scientific Research (CNRS) in Marseille, where he is working on laser-matter interaction at the Lasers, Plasmas and Photonics Processes laboratory (LP3). He received a BS in Physics from the University of Rouen (France), a MS in Optics and Photonics from University of Paris-Sud and a PhD in Physics from Ecole Polytechnique in Paris. Before joining CNRS, he has been a laser process engineer for The Swatch Group Research and Development and a scientist at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. His current interests are on ultrashort-pulsed, laser-induced modifications in transparent materials, studying the fundamental interaction mechanisms and developing tools for increased functionalization of these media.
