Abstract: The paper considers results for strongly doped turned to a single domain state crystals LiNbO3: Mg(5,03 mol % MgO and LiNbO3:Mg ( 4,75 mol % MgO ). Magnesium concentration in these crystals is close to each other and to threshold ≈5 mol % MgO . Crystals were grown from a charge synthesized using precursor LiNbO3:Mg (homogeneous doping method) and from a charge obtained at a direct addition of magnesium to the charge (direct doping method). Complex studies were carried out by Raman spectroscopy and laser conoscopy. Compositional homogeneity and some optical properties of studied crystals are considered. Homogeneous doping with precursor Nb2O5:Mg method allows us to obtain heavily doped LiNbO3:Mg single crystals with low coercive field and more compositionally homogeneous than method of direct melt doping with magnesium. In this case, a more uniform distribution of the dopant in homogeneously doped crystals begins to form at the stage of Nb2O5:Mg precursor synthesis during the formation of chemically active complexes that predominantly determine the oxygen-octahedral structure of the Nb2O5:Mg precursor.

Keywords: lithium niobate crystal, homogeneous and direct doping, Raman scattering, laser conoscopy
