Research Interests:

The ultimate goal of our activity is to realize laser fusion as a next generation energy source by creating plasmas with one thousand times solid density and a temperature of one hundred million degree Kelvin. On the way towards this goal, we study radiation hydrodynamics and high-density plasma physics (Fermi degeneracy and strongly coupled plasma) as physics basis of laser fusion. We also study unexplored physics by using a peta (ten to the fifteenth)-watt laser.

Research areas:

Fast ignition physics
Diagnostics development for ICF plasmas
Hydrodynamic instabilities and laser-plasma interactions on ICF plasmas
High energy density physics with intense lasers
