Special Session 1: Laser Ablation and Processing in Liquids
Prof. habil. Dr.-Ing. Stephan Barcikowski, Center for Nanointegration Duisburg-Essen (CENIDE), University of Duisburg-Essen, Germany
Prof. Katharine Tibbetts, Chemistry Department, Virginia Commonwealth University (VCU), USA
Prof. Hiroshi Yoshikawa, Osaka University, Japan
Prof Leonid V. Zhigilei, University of Virginia, USA
Lasers and liquids form a beautiful liaison: Laser synthesis and processing of colloids is an emerging field, including laser ablation, photochemistry, fragmentation, melting in liquid to create nano- and submicron particles with unparalleled properties, as well as crystal growth and light-guided synthesis in liquids. Application of laser-made nanoparticle building blocks has recently approached commercialization in the field of catalysis, and first successful in vivo bio-applications have been demonstrated. In addition, fundamental theoretical and experimental studies to discover the underlying plasma physics, non-equilibrium chemistry, and particle formation mechanisms drive this comparably young field. You are highly welcome to this special session, to present, meet, and vividly discuss recent progress with your peers!
Special Session 2: Machine Learning and Simulation for Laser Processing
Prof. Kenichi Ishikawa, The University of Tokyo, Japan
Dr. Tomohito Otobe, National Institutes for Quantum and Radiological Science and Technology, Japan
Dr. Thibault J.-Y. Derrien, HiLASE Centre, Czech Republic
Laser processing is flexible with many tunable parameters such as wavelength, pulse duration, pulse energy, and scan speed. Today, these parameters are optimized by human experience and intuition. In this special session, to meet the mass customization need in the coming super smart society, we discuss alternative approaches driven by data, artificial intelligence, and numerical simulations (TDDFT, PIC, MD, CFD, etc.) that highly integrate cyberspace and physical space (CPS). In addition, understanding laser processing belongs to multiscale and multidisciplinary cutting-edge science. The exploration of such strong laser matter interaction by combining data-driven, theoretical, and experimental techniques will advance smart laser processing.
