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.
