摘要
对电场极化后薄膜材料与体材料二阶光学非线性的比较研究表明 ,二者具有相同的极化和弛豫特性 .分析了束缚电荷的形成及其对二阶光学非线性的影响 ,定性地从理论上指出 。
By comparing the second\|order optical nonlinearity of electrically poled glass film and bulk glass samples, it was shown that both of them have similar poling and decay behavior. After analyzing the formation of bound charge and its influence on the second\|order nonlinearity of glass, a qualitative model was proposed, indicating that the electric field induced by the bound charge plays an important role on the poling and decay of both film and bulk glass.
