摘　　要：制备了以分散红73为客体的PMMA掺杂型有机聚合物薄膜样品,对之进行了全光极化特性的研究,极化使薄膜产生二阶非线性,种子光的强度越大,其二阶非线性极化率达到饱和值越快;种子光的位相差、相对强度比、光场强度比等因素影响薄膜的二阶非线性的优劣。The doped film sample of organic polymer PMMA using disperse red 73 as guest dye was fabricated and all optical poled. The stranger the intensity of the two writing light beams are, 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 of phase, the ratio of intensities of light beams, the ratio of intensity of optical fields of the two writing beams.
