溶胶-凝胶法制备非线性光学材料是一种新型的光学材料。将二阶非线性光学活性分子N-（4-硝基苯基）-（s）-脯氨醇以较高浓度掺杂到无机氧化物基质中。电场极化成功地引入了二阶非线性所需的非中心对称性。使用原位极化的研究允许制定的条件下，实现稳定的极化取向。二次谐波产生和电光调制的研究已经进行了这种材料。
The sol-gel-processing technique has been used to prepare a new material for nonlinear optics. The second-order nonlinearoptically active molecule N-(4-nitrophenyl)-(s)-prolinol has been doped to an inorganic oxide matrix in relatively highconcentration. Electric field poling was successfully employed to introduce noncentrosymmetry required for second-order nonlinearity. Studies using in situ poling allowed the formulation of conditions under which stable poled orientation was achieved. Second harmonic generation and electrooptic modulation studies have been conducted on this material.
