Abstract:

The angular-distribution parameters of the photoinduced scattering of light at a wavelength of 476.5 nm are used to determine the photovoltaic and diffusion field in nominally pure single crystals of stoichiometric composition (R=Li/Nb=1), grown from the melt with 58.6 mol% LiO₂ (LiNbO₃ stoich.), in nominally pure single crystals of congruent composition (LiNbO₃) in congruent single crystals doped with Cu²⁺, Zn²⁺, Gd³⁺, Y³⁺, Er³⁺, B³⁺, (Cu²⁺+Gd³⁺), and (Ta⁵⁺+Mg²⁺). The photoinduced variations of the refractive index of the crystals are determined.
