title: [Nonlinear optical absorption characteristics of a novel organic material ZnTBP/CA/PhR].
abstract: 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.
