Comparison of the acentric properties for the oxide crystals

Abstract

The indistinct empiric linear correlation between values of nonlinear optical (NLO) and piezoelectric properties, spontaneous polarization and NLO-properties has been established for noncentrosymmetric (NCS) oxide crystals. But nonlinear empiric correlation with the maximum has been found between piezoelectric - electrooptic, and piezoelectric - non-linear optical properties of these ones. These data has been useful at search of the most optimal materials for optoelectronic devices.
