一种新的双偶氮染料掺杂聚合物薄膜的光致双折射及偏振全息的研究
Photo-induced Birefringence and Polarization Holographic Recording of Polymer Film Doped with a New Kind of Bisazo Dye
摘要
Abstract
A new kind of bisazo( BA1 ) was synthesized as a material candidate for perpetual information storage application. When the sample was pumped by the beam of 532 nm, almost half of the BA1 molecules undergo a reversible trans-trans to cis-cis isomerization in the polymer matrix, resulting in photo-induced birefringence. Hence,the dependences of photo-induced birefringence and the transmission signals on the pumping beam intensities in BA1 doped poly ( methyl methacrylate) (PMMA) film were studied. It is shown that transmission signals increase with the enhancement of pump beam intensities. Here the two linear polarized beams with parallel state (SS) and orthogonal state (SP) were used to investigate holographic storage. It can be clearly seen that the diffraction efficiency of SP grating much higher than that of SS configuration.关键词
