Abstract

The Raman spectrum of LiNbO3 has been measured for various scattering configurations in crystals with different compositions. The comparison between spectra recorded for congruent and the nearly stoichiometric crystals shows significant differences in the shape and the number of Raman peaks. The analysis of results may be used to describe a complete vibrational modes of the long-wavelength optical phonos in LiNbO3 crystals.
