Title: Ultrafast non-diffractive beams with tunable dispersion; opportunities for smart laser material processing
Prezintă: Razvan Stoian, Laboratoire Hubert Curien, Université Jean Monnet, St-Etienne, France
Abstract: The lecture will follow the latest developments in ultrafast laser micro- and nano- processing using engineered beams. It will summarize the major achievements in the quest for optical resolution [1]. The talk will focus on a specific class of beams with non- diffractive properties and the possibility to perform spatial, temporal or vectorial manipulation in order to achieve a significant level of process control. Examples will be given to their specific interaction with matter and their capability to structure materials on extreme scales. A dynamic time-resolved view of the structuring process will be given, emphasizing the potential for feedback and control. Their capacity to modify matter in a user-defined way and on the smallest scales is an essential brick into smart laser material processing.
