We accurately measure the electro-optic (EO) coefficients of undoped and 1.7 mol% MgO-doped stoichiometric LiNbO3 (SLN) using high-quality crystals and a reliable AC-field applying method. The EO coefficients at the wavelength of 633 nm are determined to be r(33) = 30.2 +/- 0.6 pm/V and r13 = 9.1 +/- 0.2 pm/V for undoped SLN, and r(33) = 29.8 +/- 0.2 pm/V and r13 = 9.1 +/- 0.04 pm/V for MgO-doped SLN. The obtained values are found to be nearly the same with those for congruent LiNbO3.
