Popis:	It is shown that application of B2O3 as a flux allows one to obtain nominally pure composition-homogeneous LiNbO3 crystals characterized by high, close-to-stoichiometry ordering of structural units of the cation sublattice and high resistance to laser radiation. It have been established by calculations that boron can be incorporated into faces of oxygen tetrahedra of the LiNbO3 crystal structure. Trace amounts of boron in the LiNbO3:B crystal structure suppress to a great extent the formation of NbLi point defects. At the same time, boron distorts significantly the oxygen framework of the LiNbO3 crystal structure and thus changes the polarizability of oxygen octahedra, which determines the nonlinear optical properties of the crystal.
