Outline of Final Research Achievements

Elementary technology for generating intense circularly-polarized attosecond pulse at the light-matter interaction region is developed. The improvement of the equipment for characterizing the temporal profile of attosecond pulses are conducted and the signal-to-noise ratio is improved. With the future improvement of developed elementary technology, the attosecond pulses with different polarization can be generated exclusively at the light-matter interaction region. In addition, ultra-high vacuum compatible velocity map momentum imaging apparatus composed of multiple cylindrical electrodes is constructed for investigating ultrafast dynamics of chiral molecules and magnetic materials with the attosecond circular dichroism.
