摘　　要：测定了新型光功能有机材料锌 四苯并卟吩 巴豆酸 苯氧树脂 (Zn Tetrabenzoporphin CrotonicAcid/PhenoxyResin ,简称ZnTBP/CA/PhR)体系薄膜样品在可见光范围内的吸收谱 ,定点测量了其主要吸收谱带在激光作用下的变化情况 ,实验观察到此种材料显著的饱和及反饱和吸收现象 ,还首次观察到它的再反饱和过程。文章定性分析了变化过程中的物理机制 。The measurement of optical absorption spectrum in visible light range of a novel organic material Zn-tetrabenzoporphincrotonic acid/phenoxy resin (ZnTBP/CA/PhR) is reported in this paper. The nonlinear absorption property of the sample illuminated by lasers with different wavelengths was studied. And the absorption alteration and kinetic process of the major spectrum bands were observed. The saturation absorption (SA) and reverse saturation absorption (RSA) appeared as the input fluence increased, and re-reverse saturation absorption process of the material was demonstrated in the experiment. These properties occurred in a broad range of visible spectrum. The paper qualitatively analyses the physical mechanism during the whole course. Based on the nonlinear absorption characteristics, we showed some applications in photonics field of ZnTBP/CA/PhR.
