| Research Abstract |
Since 1982, collaborating with Max-Planck Institute of Quantum Optics in Germany, we have studying the physics of the generation of x-ray with lasers and its confinement in a cavity. We have made great progress on the measurement technique of absolute x-ray spectrum, the physics of radiation transport in high density plasmas and radiation hydropynamics. The confinement of the laser produced radiation in cavity has demonstrated and the Planck-radiation of 2.5Mega-degree Kelvin, which is the highest radiation temperature in laboratory, has achieved. In this fiscal year, the physics of the energy transport in high density plasmas produced by laser-produced x-ray, especially, propagation of radiation thermal wave, shock wave, and reemission are studied, and its industrial application is also investigated.
From the view point of the industrial application of the high intense X-ray generation, the Japanese-German workshop on Femtosecond Lasers and High-Intensity Applications was organized by Institute of Laser Engineering, Osaka University and Max-Planck Institute of Quantum Optics. The main topics were as follows.
(1) Femtosecond lasers in inertial confinement fusion
(2) Harmonic generation from solid surfaces
(3) Femtosecond laser development
(4) Harmonic generation in gases
(5) Pico-and femtosecond laser pulse propagation
(6) Numerical simulation of relativistic laser-plasma interaction
(7) Absorption of femtosecond laser pulses by solids
(8) Coherent and incoherent x-rays and their diagnostics
(9) Atomic physics in high intensity field
To investigate the project LASER2000 on Germany, and to know the status-quo of the laser application in industry, after the workshop, we have visited Hanover Technical University, Hanover Laser Center, Berlin Technical University, Max-Born Institute, and som industrial companies.
