英文摘要
Generating light pressure force reaches the giga bar, when the material is irradiated with the ultra high-strength laser. The material condition is measured by utilizing characteristics of such laser beam, and it is possible that it generates the high-speed electrojet and perforates in the plasma, concerning the state equation. Related to Equation of State, multilayered flyer was demonstrated for the first time to establish the method for obtaining the state equation data.As a laser plasma interaction phenomena, focusing ultraintense laser light into a tiny focus, a stable self focusing was observed. This knowledge supports important basic physics for the new method verification of fast ignition of the laser fusion. The high evaluation was got even in the world. It is based on the fast electron accelerated by light pressure force of ultra high-strength laser beam. The jet phenomenon over the 4mm length was observed for the first time. It can become astrophysics and important basic data of the high-speed ignition.
