  • Nonlinear Optical Phenomena
  • Raman Scattering
  • Femtosecond Pump-Probe Spectroscopy
  • Terahertz Time-Domain Spectroscopy


  • Research of hydrogen-bonding liquid by terahertz time-domain spectroscopy
  • Research of electron lattice interaction by coherent phonon
  • Research of carrier dynamics in semiconductor


In our laboratory, we study photo-excited state of material, its relaxation process and optical nonlinear phenomena associated with them. Using special laser equipments, we perform femtosecond pump-probe spectroscopy, Raman scattering, and terahertz spectroscopy and so on. Typical samples are semiconductors, liquids and low dimensional spin system, and low temperature and high pressure conditions are applied if necessary. From these measurements, the basic physical properties of the photo-excited states of these materials will be clarified.
