Abstract

In order to obtain the optical limiting materials with broad protective wavelength and high optical transmission as well as quick response, we synthesize three derivatives of alkoxy phthalocyanine Pb. The structures of these derivatives were characterized by means of IR, 1HNMR spectra and elementary analysis. Mix the three derivatives of alkoxy phthalocyanine Pb into the Monomer of MMA respectively; the phthalocyanine Pb / polymethy methacrylate (PMMA) that are polymers with non-linear optical properties are prepared. The absorption spectra of the polymers in the visible range (200~800nm) are measured to determine their Q-bands. It is found that there is high possibility having the third-nonlinear optical limiting effect for the polymers. The non-linear reverse saturable absorption and optical limiting measurements of the polymers were performed with a frequency-doubled Q switched Nd:YAG laser with 8ns laser pulse at wavelength 532nm. The factors that affect the performance of reverse saturable absorption and optical limiting of the polymers were discussed. A phenomenological model is used to describe the optical limiting phenomena.
