Abstract

The linear and nonlinear optical properties of Schiff Based compound, N-salicylidene-aniline, dissolved in organic solvents with varying dielectric constants using different concentrations are reported. Their nonlinear optical properties have been investigated by Z-scan technique with picoseconds laser pulses. The nonlinear refractive index values obtained for solutions containing 6% to 48% of N-salicylidene-aniline in toluene fall in the range -1.87 to -5.6 x 10-12 cm2/W, while the nonlinear third order susceptibility χ(3) is in the range -3.4 x 10-11 to -1.41 x 10-10e.s.u..
