摘　　要：研究卟啉材料的激光防护特性.基于卟啉-蒽化合物的分子结构特点及其光子吸收截面计算公式,研究了卟啉-蒽化合物的双光子和三光子吸收特性.结果表明,卟啉-蒽化合物具有很好的非线性光学吸收效应,其光学吸收谱可以覆盖很宽的波长范围,这种非线性光学吸收效应可以用于抵御不同波长激光武器的攻击.Laser protection characteristics of porphyrin materials are studied. Based on the molecular structure and the photon absorption cross section, the two-photon and three-photon absorption features of porphyrin-anthracene compound are analyzed. The results show that porphyrin-anthracene compounds have good non-linear optical absorption effects, having an optical absorption spectrum covering wide range of wavelength. This non-linear optical absorption effect can be applied against attacks from laser weapons with various wavelengths.
