| Abstract: | 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 porphyrinanthracene 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. |
| |
| Keywords: | two-photon absorption optical limiting effect porphyrin laser protection |
