Second Order Nonlinear Optical Effect in Ge-As-S System under the Electron-Beam
The method of Maker fringes was used and the second order nonlinear optical effect was observed in the electron-beam irradiated Ge-As-S glasses. The mechanism of this effect was discussed. It′s shown from the Maker fringes that the second harmonic intensity is strongly related to accelerating voltage, which gets a peak when the incidence of angle is ±(50°~60°).
