Outline of Final Research Achievements

We conducted experiments by tuning polarization of ultra-intense laser pulses from linear polarization to circular polarization and then irradiating into a solid target. As the results, for the circular polarization, we found that energy population bellow 0.3 MeV was increased for circular polarization. This results indicate a possibility of efficient plasma heating in comparison with usual linear poralization.
