In the present work an application of z-scan technique to the study of asphaltenes is presented in order to determined their nonlinear properties. For asphaltenes toluene solution a high value of nonlinear refraction index (n 2=6.04 × 10 -12) it is obtained. Strong dependence of the two photon absorption coefficient (β) with the input intensity was observed for higher solutions concentration, which can be explained by molecular aggregation.
