摘要
本工作研究了在聚苯乙烯八乙基卟啉永久性光谱烧孔材料上进行光谱相位编码时域光全息读写中信息写入效率随激光谱带变宽而降低的现象，建立了分子转动引起光谱再分布模型，并计算了不同写入激光线宽下信号衍射效率随曝光量的变化规律，很好地符合了实验结果．
In this paper, we present a model which describes the spectral redistribution process due to rotation of molecules in hole burning. Based on this model. the dependence of diffraction efficiency on exposure time under broad and narrow laser band are calculated, respectively. which are in good agreement with experimental results.
