abstract---
We have experienced an outstanding progress of high power laser technology in the last decade. The laser power has achieved to Peta Watt (1015W) and the laser intensity has exceeded 1020 W/cm2. The electric field of such laser is 10kV/Å and the fairly large fraction of the laser energy is converted to those for the relativistic electrons with the energy more than several MeV. Through such relativistic electrons and γ-rays stemming from the Bremmstrahlung process, a variety of nuclear reactions are induced. In the present report, I would like to review the present understanding the physical mechanism of such relativistic electron generation. Related experimental and simulation data are shown. Our trial named “Laser Nuclear Physics” is described by focusing on the topics of nuclear transmutation through the excitation of Giant Dipole Resonance (GDR). A rough estimation is done regarding the laser parameters to realize the radioactive waste transmutation with the ultra-intense lasers. |
