摘要：

Periodically-poled LiNbO3 bulk crystals with (Y, Mg), (Dy, Mg), (Nd, Mg) end (Eu, Mg) were grown along the normal to the faces {0112}. The superlattice with period 4-30 mu m was studied by chemical etching, optical microscopy and by wave dispersive X-ray microanalysis In the scanning electron microscope (SEM). The face (0112) forms thin and flat boundaries of domain and is favourable to a high stability of domain period. The distribution of Impurities in double-doped LiNbO3 crystals has the form close to sinusoid with the period corresponding to the period of regular domain structure.
