| Outline of Final Research Achievements |
The aim of this project was to break through the limitations of Ti:Sapphire laser technology by developing a next-generation high-intensity laser with high average power, and to utilize the soft-X-ray attosecond source as a tool for materials science. First, a carrier-envelope phase-stable optical parametric amplification sources in the infrared region excited by a high average power Yb;KGW laser was successfully developed. Regarding to the use of soft-X-ray attosecond pulses, transient absorption spectroscopy at the nitrogen K edge around the photon energy of 400 eV was demonstrated. New techniques for the use of intense ultrashort-pulse IR sources were explored and novel phenomena in gas-phase atoms, molecules, liquids and solids were observed.
