| Outline of Final Research Achievements |
It is going to be performed in an ultra-high peak power laser and the interaction study of the solid density material now in an extreme high intensity of 1022W/cm2. Under such an ultra-high intensity, the existence of the light noise (background light) associated with the ultra-high peak power laser becomes the extremely big problem. In this study, understanding elucidated a developmental process of the background light of the domain quantitatively at pico second time due to a diffraction grating to use at the time of ultra-high peak power laser generation and demonstrated control, restraint of the background light. Furthermore, establishment realized the generation technique of the few super low background light laser pulse so far and contributed to the quantum beam science such as a high energy particle acceleration or high field physics study by applying this result.
