摘要
制备了以分散橙25为客体的掺杂型有机聚合物PMMA薄膜样品,对之进行了全光极化研究,极化使薄膜产生诱导二阶非线性光学效应,种子光的强度越大,其二阶非线性极化率达到的饱和值越大;种子光的位相差、相对强度比、光场强度等因素影响薄膜的二阶非线性的优劣.
Using disperse orange 25 as vip dye, the doped film sample of organic polymer PMMA was fabricated and all optical poled. The stronger the intensity of the two writing light beams correspond to the faster the second order susceptibility for the second nonlinear optical effect by the all optical poling achieves the saturation. The quality of the second nonlinear optical effect in the film was affected by several factors such as the difference between phases, the ratio of intensities of light beams, the ratio of intensity of optical fields of two writing beams.
