Abstract

In the field of holographic storage, poly (methyl methacrylate) (PQ/PMMA) photopolymer doped with phenanthraquinone has the characteristics of controllable material thickness, polarization sensitivity, and simple manufacturing process, demonstrating good research value and application prospects. This paper prepared PQ/PMMA materials with thicknesses of 0.3, 0.5, 1.0, 1.5, 2.0, 3.0, and 4.0 mm, and analyzed the holographic characteristics of PQ/PMMA materials with different thicknesses, such as diffraction efficiency, photosensitivity, refractive index modulation, etc. By comparing the holographic performance parameters of materials with different thicknesses, it was found that as the thickness increases, the saturation diffraction efficiency shows a trend of first increasing and then decreasing. The 3.0 mm thick PQ/PMMA material has higher saturation diffraction efficiency and photosensitivity, providing a basis for optimizing material preparation parameters.
