| Research Abstract |
Stable carrier envelope phase stabilized high intensity few-cycle pulse is generated for ultrafast chemical reaction imaging. Ultra high vacuum compatible photo-electron photo-ion coincidence momentum spectrometer which is applicable for a pump and probe measurement using an isolated attosecond pulse as a probe pulse and an intense few-cycle pulse as a pump pulse is developed. Momentum map imaging method for improving momentum resolution of heavy fragment ions and spatial map imaging method for selecting signals only from focal region for disentangling intensity averaging are developed.
