| Abstract: | Photovoltaic and diffusion fields in nominally pure single crystals of stoichiometric composition (R = Li/Nb = 1) grown in the presence of 6 wt% K2O flux (LiNbO3 stoich. K2O) in nominally pure single crystals of complementary composition (LiNbO3), complementary single crystals doped with Zn2+, Er3+ at wavelength of 476, 514.5, 530 nm are defined according to parameters of photo induced light scattering indicatrix. Photo induced changes of crystals’ refractive index are defined. |
