Abstract

Ultrafast-time-resolved spectroscopy of ferroelectric materials and phase transitions is discussed. Impulsive stimulated Raman scattering (ISRS) experiments on optic phonon modes, including soft modes, are reviewed and new data on anharmonic phonon responses in PbTi03 are presented. Multiple-pulse ISRS excitation of lattice vibrations is also reviewed. The prospects for driving large-amplitude vibrational responses and inducing ultrafast switching between different domain orientations or different phases are discussed. The need for theoretical guidance of these efforts is emphasized.
