The effective electro-optic (EO) coefficients r(13)(E) and r(33)(E) in the wavelength range 409-3390 nm were measured for non-doped congruent LiNbO3 crystal under constant stress by using the Multiple reflection interference method, and the wavelength dispersion equation for each coefficient was obtained. Since the effective EO coefficient is related to the change of the refractive index due to the EO effect under constant stress and the change of the crystal length due to the inverse piezoelectric effect, it is a very important parameter for designing low-frequency optical devices.
