Outline of Research at the Start

X線自由電子レーザーの7×7ナノメートル集光とそれに伴う10^22 W/cm^2のピーク強度が達成された.可視光域の最先端にも比肩し得るこの超高強度X線レーザー場を用いて,本研究では,多重励起状態原子・分子物理の探索と高次の硬X線非線形光学現象の観測を実施する.具体的には,電子の多重励起が予測される7ナノメートル集光XFEL照射時に基礎とすべき励起状態を決定し,これらの知見を基に硬X線領域の高次非線形光学現象の観測を目指す.世界唯一の極限集光X線レーザーを真に使いこなし,新たな物理現象の探索へと乗り出す.

Outline of Final Research Achievements

Using a newly developed XFEL beam focused to 7×7 nm with a peak intensity of 10^22 W/cm^2, we performed a study for exploring nonlinear X-ray optical phenomena. As a result, we demonstrated the formation of a "fully ionized" state in chromium, in which all electrons were strongly photo-excited. Furthermore, in molybdenum, we achieved the first observation of a hard X-ray three-photon absorption, where three photons simultaneously interacted with a 1s electron.

Academic Significance and Societal Importance of the Research Achievements

光の特性に対する非線形応答は,現代の可視光レーザー技術や物理計測技術の中核を成している.X線領域においても非線形光学が開拓されれば,新たなX線分析技術や非線形X線光学デバイスの開発を通じて,科学計測の応用範囲を大きく拡張できる可能性がある。また本研究で得られた成果は,原子・分子物理や高強度場科学の分野における,新たな計測手法としての応用可能性を示している.
