Ultra-Intense Field Science (LF) Lab
Machine-translated · View original
A lab that explores fusion and extreme plasmas with ultra-high-intensity lasers.
AboutAbout the lab
Exploring ultra-intense field science to open new horizons toward realizing fusion energy
The Ultra-Intense Field Science group studies high-energy-density plasmas and laser fusion using ultra-intense electric, magnetic, and radiation fields created by lasers.
In fast ignition laser fusion, which is pursued at the institute, fusion fuel compressed to high density is heated in an instant by a high-intensity laser, with the aim of raising it to the temperature needed for ignition.
The lab also works on astrophysics and nuclear science using intense fields, such as studying photoionized plasmas around black holes in the laboratory.
The group is a cooperating group of the Department of Physics, Graduate School of Science, The University of Osaka, and is located at the Institute of Laser Engineering.
Key terms
- Laser fusion
- A scheme in which fusion fuel is compressed to high density and heated with high-intensity lasers to trigger fusion reactions.
- Warm Dense Matter
- A state of matter on the boundary between solids or liquids and plasma.
- Photoionized plasma
- Plasma produced when light strips electrons from atoms. Some research reproduces plasmas near black holes in the laboratory.

ResearchResearch themes
Centered on the interaction between ultra-intense lasers beyond the petawatt class and plasma, the lab studies the physics of high-energy-density plasmas found in fusion and in astronomical objects. It works on both experiments and the development of the measurement technologies that support them.
*Illustrative imageThe physics of heating plasma to ultra-high temperatures
By understanding and controlling the generation, propagation, and energy dissipation of electron and ion beams produced in the interaction between ultra-intense lasers and plasma, the lab will demonstrate heating up to 50 million degrees, the fusion ignition temperature.
*Illustrative imageExtreme plasma physics
Using lasers to create high-energy-density states in the relativistic plasma and Warm Dense Matter regimes, the lab is pioneering plasma physics under kilotesla magnetic fields and gigabar pressures. This leads to reproducing phenomena inside stars and around high-energy astronomical objects in the laboratory.
*Illustrative imageDiagnostics for precisely measuring plasmas
The lab develops measurement technologies that are essential for precise experiments. They include a hard X-ray spectrometer using Compton scattering, imaging of dense plasmas with X-ray pulses of about 1 picosecond, and electromagnetic field measurement using laser-accelerated protons.
*Illustrative imageResearch on X-rays generated by high-intensity lasers
The lab studies, from both fundamental and applied perspectives, the interaction with matter of ultrashort-wavelength light, with wavelengths from 1 to 100 nanometers, emitted by laser-driven plasmas. It uses one of the few high-intensity ultrashort-wavelength light sources in the world.
