| 摘 要： | 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 NbLi which provides the anti-site defect to Fe^2＋.
