SECOND HARMONIC GENERATION IN THE SYSTEM Ge-As-S ADN ANALYSIS OF THE POLING MECH ANISM
Ge-As-S体系玻璃中光学二次谐波发生及其极化机理分析

By the method of Maker fringes,second harmonic generation effect was first obser ved in the electron-beam irradiated Ge-As-S glasses. The poling mechanism was st udied by the method of thermally stimulated depolarization current (TSDC) and th e poled regions was found in the thin surface layer of glasses,which was the sam e as the calculated result in theory.
