Outline of Final Research Achievements |
A system for ultrafast photoelectron spectroscopy was constructed using laser high-order harmonics in extreme ultraviolet, which was successfully applied to femtosecond pump-probe real-time tracking of ultrafast electron wavepacket dynamics. The effect of electronic excitation in molecular dynamics in intense laser fields was studied by momentum imaging of dissociative ionization of UV-excited molecules. Based on the finding, a novel method to visualize electron dynamics in molecules in real time was proposed. Photoelectron spectroscopy of molecules before and after the irradiation of an intense laser pulse was performed, revealing selective excitation of specific electronic states in the laser field.
