Ultrafast Photonics Research Group

The Ultrafast Photonics Research Group pursues the direct observation and mechanistic understanding of electron and nuclear dynamics that govern the functions of materials and molecules, employing ultrashort optical and electron pulses in the femtosecond and attosecond regimes. Advances in laser technology and electron beam control have made it increasingly possible to investigate ultrafast phenomena in a time-resolved manner that was previously unattainable. Our research integrates the development of innovative laser sources for post-attosecond science, ultrashort electron beam technologies, and state-of-the-art molecular spectroscopy. Through these efforts, we seek to elucidate the dynamical processes underlying material responses, chemical reactions, and molecular functions, while establishing new scientific principles and experimental foundations that will pave the way toward controlling these processes.
