✦ Synopsis

Second Harmonic Generation was observed in the electron-beam irradiated GeS 2 -In 2 S 3 -CdS chalcogenide glasses, which were induced by the frozen-in electric field due to the electron-beam irradiation. The Second Harmonic Intensity increased with the increasing of the irradiating current and time. The stability of second harmonic generation studying showed that the χ (2) started to decay till zero when the glasses were annealed above room temperature. It was supposed that the strength of the frozen-in electric field decreased to zero during the annealing process.
