Paper Abstract

In the present work an application of z-scan technique to the study of asphaltenes is presented in order to determine their nonlinear properties. For asphaltenes toluene solution a high value of nonlinear refraction index (n2 equals 6.04 X 10-12) it is obtained. Strong dependence of the two photon absorption coefficient ((beta) ) with the input intensity was observed for higher solutions concentration, which can be explained by molecular aggregation.
