【Abstract】 The measurement of optical absorption spectrum i n visible light range of a novel organic material Zn-tetrabenzoporphin-croto nic acid/phenoxy resin (ZnTBP/CA/PhR) is reported in this paper. The nonlinea r absorption property of the sample illuminated by lasers with different wavel engths was studied. And the absorption alteration and kinetic process of the ma jor 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 sp ectrum. The paper qualitatively analyses the physical mechanism during the wh ole course. Based on the nonlinear absorption characteristics,we showed some applications in photonics field of ZnTBP/CA/PhR.更多还原
