We experimentally studied laser-hole boring with 100 ps/1 TW laser light and ultra-intense laser-plasma interactions using a 0.5 ps/100 TW laser system. Investigation into laser-hole boring was made by measurements of backscattered light spectra, x-ray image and electron density profiles in under- and overdense regions. For the first time x-ray laser light was used to directly observe the channel in the overdense plasma. We further examined short pulse laser interactions as well as the generation of high-energy particles with 100 TW laser light. Neutrons by D-D fusion reaction in the interaction plasma were measured to diagnose ion acceleration. High-energy electrons (MeV) were measured by a x-ray method.

我々は、100 ps/1 TWレーザー光を用いたレーザーホールボーリングと、0.5 ps/100 TWレーザーシステムを用いた超高強度レーザー・プラズマ相互作用を実験的に研究した。レーザーホールボーリングの調査は、後方散乱光スペクトル、X線画像、および低密度・高密度領域における電子密度分布の測定によって行われた。高密度プラズマ中のチャネルを直接観測するために、初めてX線レーザー光が使用された。さらに、100 TWレーザー光を用いた短パルスレーザー相互作用と高エネルギー粒子の生成についても検討した。相互作用プラズマ中のD-D核融合反応による中性子を測定し、イオン加速の診断を行った。高エネルギー電子(MeV)はX線法によって測定された。
