Abstract We detect the photo-induced carriers in near-stoichiometric iron doped LiNbO₃ crystal by the holographic technique. The results show that the dominant carriers are electrons in the sample with Li/Nb ratio of 0.9988. By analysis of the OH^- absorption spectra of the crystal, we contribute the electron domination in near-stoichiometric Fe-doped LiNbO₃ crystal to the existence of Nb_Li which provides the anti-site defect to Fe²⁺.
