| Research Abstract |
The aim of this study is to control actively photoinduced phase transition in strongly correlated molecular crystals, whose applications to ultrafast optical switching devices are expected. For this purpose, I developed various types of time-resolved spectroscopic system over a range from 10 fs to 100 ps, and found the quasi-stable state only created by photo-excitation and the time delay from electronic phase transition to lattice phase transition. In addition, I succeeded in finding the phenomena that photoinduced phase transition can be controlled actively through variation of excitation photon-density, coherent phonon, and electronic coherence.
