摘要
采用记录透射型衍射光栅实验方法,研究以亚甲基蓝作为光敏剂、丙烯酸和N,N’-亚甲基双丙稀酰胺共同作为单体时厚度约为180μm的光致聚合物进行多波长复用时的全息特性,结果表明:记录波长为632.8nm时,衍射效率高于40%,曝光灵敏度约为0.0083cm2/mJ;记录波长为514nm时,最高衍射效率达57%、曝光灵敏度为0.0067cm2/mJ,并且首次在488nm处获得超过50%的衍射效率,说明该光致聚合物适合多波长存储.
The multi-wavelength holographic characteristics of the photopolymer dry film with 180 m thickness,which is based on acrylic acid and N,N'-methylenebisa-crylamide as monomers,photoinitiated by Methylene Blue,was studied by recording the transmission diffraction gratings.The results reveal: Diffraction efficiency of above 40%and energetic sensitivities of 0.0083cm2/mJ was obtained by record-wavelength of 632.8nm;The best high diffraction efficiency of 57%and energetic sensitivities of 0.0067cm2/mJ was obtained by record-wavelength of 514nm;Addition,Diffraction efficiency of above 50% was obtained first at 488nm.These results show the photopolymer is adaptive to the multi-wavelength holographic storage.
