The Ultra-High Pressure Science group studies how to create ultrahigh-pressure states using shock waves that high-intensity lasers generate inside matter. The pressures obtained with lasers far exceed those at the center of the Earth (about 3.5 million atmospheres), reaching conditions inside Jupiter and at the center of the Sun. The lab is pioneering methods that control shock waves in time and space to create states above 1 billion atmospheres, and applies the resulting states to research on the interiors of the Earth and planets. It is also working on applications to materials processing technologies such as laser peening, and on developing fusion ignition schemes driven by shock waves.

The Extreme Plasma Engineering Division (Kuramitsu Lab) studies plasma science using high-power lasers. The lab recreates, on a small laboratory scale, the ultra-high-temperature, high-pressure world like the center of the Sun and the high-energy-density world found in distant space, in order to probe the mysteries of the universe. Students take part in research projects as members of the research team, and also join experiments at large laser facilities on and off campus. The lab is one of the research groups of the Institute of Laser Engineering, and its graduate students belong to the Division of Electrical, Electronic and Infocommunications Engineering in the Graduate School of Engineering.

The Laser Fusion Systems (LFS) group, at the Institute of Laser Engineering, Osaka University, aims to design a laser fusion power reactor based on an understanding of materials. On the lab's website, the group is introduced as the "Shigemori Lab," which conducts research and development on igniting and burning fusion fuel with lasers, and research and development on laser processing using power lasers. According to the website, the Shigemori Lab is a cooperating research group of the Division of Sustainable Energy and Environmental Engineering in the Graduate School of Engineering. In addition to experiments using Osaka University's large laser facility Gekko XII, the lab also conducts experiments at facilities such as Kyoto University and Tohoku University.

Fusion Energy Dynamics (FED) belongs to the Laser Fusion Science Division of the Institute of Laser Engineering, and studies how energy moves inside a laser fusion reactor. Part of the energy generated by fusion reactions circulates through the reactor as energy and as fuel, changing form along the way. The challenge is to build a laser fusion reactor system that satisfies both of these at the same time. The lab works on blankets, fuel production, digital twins, and reactor design.
Nobuhiko Sarukura, Professor

The Sarukura-Shimizu Lab works on developing next-generation light sources in pursuit of the limitless possibilities of optical technology. In addition to research on all-solid-state tunable ultraviolet lasers and high-intensity terahertz wave sources, the lab also conducts research with nanotechnology and biotechnology in mind. The lab focuses not only on basic research but also on applied research. At the Institute of Laser Engineering, the lab is introduced under the name "Extreme Materials Science (LAM)", and it belongs to the Laser Applied Engineering area of the Quantum Energy Engineering Division in the Department of Environmental and Energy Engineering, Graduate School of Engineering.

The Nonequilibrium Radiative Plasma Theory (THR) Lab studies "high-energy-density states", in which matter is heated to extremely high temperatures in an instant by intense laser light, using theory and computer simulation. A high-energy-density state is a dense, high-temperature state of matter, like the interiors of stars and planets. At extremely high temperatures, matter turns into plasma, fast electrons and ions are generated, and nuclear fusion reactions and X-ray and gamma-ray radiation occur. By understanding the physics taking place inside, the lab hopes to contribute to estimating the interiors of stars and to realizing laser fusion and high-energy particle accelerators.

The Open-System Plasma Theory (TOP) Lab studies the physics of "high-energy-density plasmas", states of matter with high density and temperature, using theory and simulation. Plasma is a many-body system in which charged particles move collectively; it generates electromagnetic fields and produces phenomena not seen in neutral matter. The lab builds numerical simulations and theoretical models for plasmas that can be created with large, high-intensity laser facilities. The lab is located within the Institute of Laser Engineering at Osaka University, and is a cooperating research group of the Department of Physics, Graduate School of Science.

The Physics Informatics Lab studies the implosion in laser fusion and the related fundamental laser-plasma physics through computer simulation. In the newly proposed fast ignition scheme, compression lasers implode the target, and the resulting dense plasma is further heated by an ultra-intense laser to aim for ignition. Because these are strongly nonlinear phenomena, simulation is important in addition to theoretical analysis, and the lab also develops computational codes best suited to the analysis. In the institute's list of research groups, the lab is introduced as a group that uses computational science and AI to understand plasmas from fundamentals to applications.
