Volume polarization holographic recording in phenanthrenequinone-doped poly (methyl methacrylate) photopolymer is obtained. Photoinduced birefringence in a 2 mm thick sample is measured by a phase-modulated ellipsometry. The birefringence induced in this material by linearly polarized beam at 514 nm reaches 1.2×10(-5). In addition, ability for recording volume polarization grating using two different polarization configurations is demonstrated and compared. The experimental results show that the diffraction efficiency of the hologram reaches to ∼40% by using two orthogonal circularly polarized beams.
在芘醌掺杂聚甲基丙烯酸甲酯光聚合物中获得了体积偏振全息记录。通过相位调制椭圆偏振法测量了 2mm 厚样品中的光致双折射。在这种材料中，514nm 线偏振光束诱导的双折射达到 1.2×10(-5)。此外，还演示并比较了使用两种不同偏振配置记录体积偏振光栅的能力。实验结果表明，使用两个正交圆偏振光束，全息图的衍射效率达到约 40%。
