Rough estimation of the non-linear susceptibility in some amorphous chalcogenides

Abstract

Using generalized Miller's rule and single oscillator model of Wemple and Di Domenico, simple relation is derived for estimation of the non-linear susceptibility (X(3)). This ralation provides reasonable agreement between the calculated and experimental X(3) values for more than 90 glassy oxides. Prediction of X(3) values for chalcogenide galsses indicates that non-linear susceptibility can reach up to X(3) = 2 x 0.1 esu for some telluride glasses.
