In the Nonlinear Laser Spectroscopy Group, the present research
interest has been focused on the phonon physics, in particular,
3-phonon process in both crystalline and amorphous materials. The
temperature dependence of hypersonic attenuation and the low
energy excitation in amorphous materials has been investigated by
using nonlinear laser spectroscopy such as Brillouin gain
spectroscopy and Impulsive Stimulated Thermal
Scattering. On-going research works: Correlated fields hole
burning spectroscopy in Tm:YAG; Development of high precision
Brillouin gain spectrometer ; Study of hypersonic attenuation in
crystals and glasses; Light beat fluorescence line narrowing
spectroscopy; Ultra-fast spectroscopy in organic materials;
Development of ECDL(semiconductor laser).
