Microscopic characteristics of cladded crystal fiber are analyzed by X-ray diffraction, Laue X-ray diffraction and scanning electron microscopy, it is found that magnesium-ion indiffusion does not affect the single crystal structure and the domain structure of the magnesium diffused crystal fiber. It is found for the first time that MgO-rich layer in the magnesium diffused LiNbO〓 surface layer exhibits the crystal structure of an unknown compound from the Li-Mg-Nb-O ternary system and MgNb〓O〓. It is proposed for the first time that this unknown compound and MgNb〓O〓 in MgO-rich layer are the real sources of magnesium-ion indiffusion LiNbO〓. Their appearance indicate that MgNb〓O〓 is in the surface layer of MgO-rich layer, the unknown compound is in the subsurface layer and beneath where the MgNb〓O〓 is located, and these compounds have obviously preferred orientation.
