Abstract
We discuss the study of three chalcogenide glasses of high third-order nonlinear electric susceptibility, AsSe4,GeSe4, and GeAsSe8. We measured the strain optical coefficients, and we determined dispersion equations of the refractive index from previously published measurements. From these data, we performed a theoretical study of a new scheme for third-harmonic generation in a glass where phase matching is created by a photoelastic effect. A complete symmetry analysis based on Curie principle allowed us to define the configuration of polarization of the interacting waves, leading to a nonzero cubic effective coefficient. The generated third-harmonic intensity is then calculated.
