Abstract
Investigations of the defect structure of a gradient-activated stoichiometric LiNbO3:Mg2+, Cr3+ crystal, in which the chromium concentration has a constant value of 0.1 at. % along the crystal growth axis, and the magnesium concentration changes smoothly from 5.5 to 2.0 al. %. The threshold concentration of Mg2+ ions (2.35 at. %) in these crystals with a concentration width of change in the center composition (Cr optical center and its nearest neighbors) of 0.09 at. % Mg2+ ions is established..
