使用两束正交线偏振 633 nm He-Ne 激光束和随后的退火，研究了具有偶氮苯侧基的聚合物液晶薄膜中的偏振全息记录。尽管聚合物材料的电跃迁几乎是非共振的，但仍创建了稳定的纯偏振光栅，其一级衍射效率大于30%。
Polarization holographic recordings in polymer liquid-crystal films with azobenzene side groups were investigated using two orthogonal linearly polarized 633 nm He-Ne laser beams and subsequent annealing. Although the electric transitions of the polymer material were almost off-resonant, stable pure polarization gratings were created with a first-order diffraction efficiency greater than 30%.
