Webinar: Advanced Material Processing with Ultrashort Pulsed Lasers Through a Detailed Description of the Fundamental Multiscale Physical Processes

CaSToRC, the HPC National Competence Centre,
invites you to the SimEA Online Seminar Series

About the SimEA project Seminar Series

The SimEA project Seminar Series aims at promoting and disseminating scientific knowledge, focusing on Computational Science and Engineering, by featuring prominent researchers from around the world presenting their views and addressing key questions. 

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 810660.

Abstract

Over the past decades, the use of ultrashort pulsed laser sources for material processing and associated laser-driven physical phenomena has received considerable attention due to the important technological applications, in particular in industry and medicine. Various types of surface structures generated by laser pulses and, more specifically, the so-called laser-induced periodic surface structures (LIPSS) on solids have been studied extensively. 

Several laser-driven processes, including energy absorption, photo-ionization processes, electron excitation, electron-relaxation mechanisms, phase transitions and/or thermomechanical effects, resolidification, and mass ejection are some complex and highly nonlinear phenomena that need to be described and be coupled into a multiscale physical theoretical model to explain the self-organisation-based LIPSS formation. A thorough understanding of these laser-driven physical phenomena are expected not only to lead to an enhanced control of the laser energy for numerous potential applications but contribute to the fundamental understanding of the underlying physical processes. Hence, it is of paramount importance to develop appropriate modelling schemes that couple together processes on various timescales and provide precise and consistent description of the electron dynamics and lattice response following irradiation of a solid with ultrashort pulses.  

To address the above challenges, Dr. Tsibidis will briefly present his research efforts towards the state-of-the-art in the development of a multiscale physical model to efficiently describe surface modification processes on various types of materials.

About the Speaker

George D. Tsibidis graduated from the Physics Department at the University of Athens and he received his PhD in Theoretical High Energy Physics at the University of Sussex. After spending some years in the Mathematics Institute at the University of Warwick (UK), he joined the Institute of Electronic Structure and Laser at FORTH as a Research Scientist.

His interests include theoretical approaches related to ultrafast laser interaction with materials and laser processing.
