Obtaining and studying photorefractive and optical properties of lithium niobate single crystal co-doped with gadolinium and boron
摘要
A technological scheme has been developed for producing a uniform single-phase LiNbO3:Gd:B charge of a given composition. The charge is necessary to grow using the Czochralski method structurally and optically uniform lithium niobate (LN, LiNbO3) crystals co-doped simultaneously with gadolinium and boron. Studies of the optical and photorefractive properties of the resulting single crystal have been carried out by express assessment methods based on the number of scattering centers in the crystal volume photorefractive light scattering and laser conoscopy. Research indicates high optical quality of the crystal and its promising use as a nonlinear optical material.
