DEPENDENCE OF ELECTRO-OPTICAL COEFFICIENTS OF THE LITHIUM NIOBATA LEADED CRYSTALS FROM ZINC CONCENTRATION
The electro-optical coefficients r <sub>22</sub>, r <sub>е</sub> of doped lithium niobate crystals are determined by the interference-polarization method as a function of zinc concentration in the range 0,018-0,88 wt. %. The dependence of the electro-optical coefficient on the zinc concentration is nonlinear. The values r <sub>22</sub>, r <sub>е</sub> are determined.
