Short description:

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

Session organizers:

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

Short description:

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.
