对分散红１（ｄｉｓｐｅｒｓｅ ｒｅｄ １ ，缩写为ＤＲ１） 掺杂聚甲基丙烯酸甲酯（ＰＭＭＡ）／ 凝胶玻璃复合材料的光学二阶非线性及其热稳定性进行了研究．分析了实时极化二次谐波产生（ＳＨＧ） 的动态过程及影响光学二阶非线性的因素．同时对影响ＤＲ１ 掺杂复合凝胶玻璃材料的光学二阶非线性强度的因素进行了分析
The optical second order nonlinearity and thermal stability of PMMA / gel glass composites doped with disperse red 1 (DR1) were studied. The dynamic process of real-time polarized second harmonic generation (SHG) and the factors affecting the optical second-order nonlinearity are analyzed. At the same time, the factors influencing the optical second-order nonlinearity of DR1-doped composite gelled glass were analyzed
