Using electro-optic coefficients in LiTaO₃ measured at wavelength 632.8 nm and the wavelength dispersion curves of EO coefficients in LiNbO₃, low- and high-frequency EO dispersion curves in LiTaO₃ were deteremined. The low frequency dispersion curves of r₁₃ and r₃₃ in LiTaO₃ were in good agreement with the EO coefficient values measured by Casson et al. [J. Opt. Soc. Am. B/21 (2004) 1948] at the near infrared region.
