| Outline of Final Research Achievements |
We aimed at generating of GW-scale isolated attosecond pulses in the soft x-ray region, and deveoped a high-power 3-channel waveform synthesizer. By preciously stabilizing carrier envelope phases, relative phase jitters and delay jitters in our waveform synthesizer, we succeeded in improving the output stability of isolated attosecond pulses in the soft x-ray region. In addition, we expanded our multi-color gating method for generating isolated attosecond pulses, and proposed a new generation method combining circularly polarized light which called generalized infrared double optical gating (GIRDOG). GIRDOG has an ability to generate GW-scale isolated attosecond pulses.
