Abstract

The nonlinear refraction index n₂ and the reverse saturation absorption (RSA) coefficient β of a series of hydroxylphenyl porphyrin have been measured using single beam Z-scan technique with a 8 ns laser pulse at 532nm and the third-order nonlinear susceptibility χ⁽³⁾ of the samples are calculated. It is seen that a series of hydroxylphenyl porphyrin have large value of the reverse saturation absorption and cubic nonlinear refraction. The effects of molecular structures on the third-order nonlinear optical properties were discussed. Experimental results show that the effects of different numbers and different positions of substituent to the nonlinear refraction of porphyrin are evident.
