Abstract

The in situ refractive index of LiTaO3  single crystals was obtained by Brillouin scattering under a backscattering configuration. Combined with the platelet scattering configuration, all the independent physical constants, namely six elastic constants, four piezoelectric constants and two dielectric constants, were obtained by conducting the same X-cut LiTaO3  single crystal. The results agreed well with the reported values.

Key words： Brillouin scattering; LiTaO$_{3}$ single crystal; refractive index; physical constants
