Abstract
The coefficients of the second-order nonlinear optical tensor (dij) for lithium niobate crystals doubly doped with magnesium and zinc by different methods of impurity introduction were calculated.Impurity concentrations (Zn:Mg) in crystals were 3.74:1.09 mol. % in case of direct doping, 3.83:0.97 mol. % in case of homogeneous doping. It was shown that the efficiency of radiation conversion with second harmonic generation in a homogeneously doped crystal is higher than in a crystal obtained by the direct doping method.
