Abstract
We report on photoinduced second-harmonic generation (SHG) in chalcogenide glasses. Fundamental and second-harmonic waves from a nanosecond pulsed Nd:YAG laser were used to induce second-order nonlinearity in chalcogenide glasses. The magnitude of SHG in glass was larger than that of tellurite glass with a composition of (mol.%). Moreover, no apparent decay of photoinduced SHG in glass was observed after optical poling at room temperature. We suggest that the large and stable value of is due to the induced defect structures and large of the chalcogenide glasses.
