Abstract: | The optical limiting action of C60 doped poly(ethylacetylenecarboxylate) polymer has been carried out using Pulse Nd-YAG laser at 532 nm as the source of excitation. The optical limiting measurements were performed at three different doping concentrations. The optical limiting efficiency of the C60 doped poly(ethylacetylenecarboxylate) polymer was studied at various doping concentrations, the threshold limiting fluence at 0.15 J/cm2 was observed with transmission of about 89%. An explanation based on the combination of two-photon absorption and reverse saturable absorption was proposed for its nonlinear optical absorption behavior. |
