| Outline of Final Research Achievements |
In this research, we investigated the scheme on ultra-high pressure condition of gigabar (1 billion atmospheres) with high-intensity laser irradiation. We also have constructed the platform that contributes to high-energy density scientific research, and explore its application fields. During the four-year research period, the development of this pressure generation scheme in the Gigabar regime and its physical mechanism were elucidated by two major approaches. (1) We have developed a scheme that effectively utilizes hot electrons generated by laser plasma interactions in pressure generation due to ablation generated by high-intensity laser irradiation. (2) We succeeded in obtaining an ultra-high pressure state by irradiating a sample with a nanowire structure on the surface with an ultra-high intensity laser and improving the absorption rate on the sample surface.
