| Outline of Final Research Achievements |
By compressing the high-energy mid-infrared pulse to two cycles using our uniquely developed DC-OPA and combining this with the loose focusing method, we generate high-energy attosecond high-order harmonics in the water window region. Furthermore, an optical synthesizer consisting of multi-cycle three-wavelength laser pulses realizes an almost single-cycle harmonic driving field and generates a GW class isolated attosecond pulse with high efficiency. We also succeeded in measuring the waveform by using an attosecond streaking method. In addition, we developed a new method for generating circularly polarized light pulses and an attosecond transient absorption simulator for application to the investigation of attosecond electron dynamics in atoms and molecules.
