Paper Abstract

Spectra of the Raman scattering (RS) by transverse and longitudinal A1-vibrations in crystals of the lithium niobate and lithium tantalate are investigated at room and liquid helium temperatures. An essential decrease of the RS- linewidths for scattering by A1T-phonons is found in the course of deceasing from room to liquid helium temperature. The obtained results show that coherent excitation of polariton modes in ferroelectrics is a promising method for generating the frequency-tunable submillimeter-band radiation.
