Abstract
In this work we present the study of nonlinear optical properties of Au nanoparticles suspended in different solutions, using the z-scan technique. Thermal lens model and Shiek-Bahae formalism were used to determine the nonlinear properties. Parameters as the sign and nonlinear refractive index n2 , nonlinear absorption coefficient (β) and dn/dt were found. Analyses of changes in these parameters using different solutions with the same concentration of Au nanoparticles are shown.
