摘要：

Results of theoretical analysis of dielectric permittivity perturbations in lithium niobate crystal with periodically poled domain structure are presented. The deviation of periodical domain structure duty cycle from 0.5 and the electric bias field created by point defects are taken into consideration. The isotropic diffraction with many maxima is considered as a boundary problem for symmetric propagation of probing beam. The agreement between numerical analysis and experimental study of the isotropic diffraction patterns performed for laser beam polarized along domain walls and propagating along polar axis through the periodically poled domain structure confirmed the proposed theoretical model.
