Abstract
By means of femtosecond optically heterodyne-detected optical Kerr eff ect and polarization-selective impulsive stimulated light scattering t echniques, we have directly observed the fluctuation and low-frequency phonon structures in disordered systems over a wide frequency range. Various disordered materials such as liquid, polymer and glass are cho sen for the sample and their characteristics are discussed.
