Research output: Contribution to journalConference articlepeer-review


The poiar low frequency vibrational and relaxational modes crucial to understanding the structure and phase transitions of ferroelectric perovskite crystals are examined using impulsive stimulated Raman scattering (ISRS). At wavevectors near the Brillouin zone center, these modes are strongly coupled to light, and the pure optic mode behavior is deduced from the wavevector dependence of the mixed phonon-polaritons.
