Using a thermal lens experimental setup, thethermal diffusivity of R6G in presence of gold nanoparticles with Au different concentration was measured. Theresults show that, the thermal diffusivity of R6G dye mixed with gold nanoparticles increases with the increaseof particle metallic concentration, enhancing the thermal diffusivity in the solution. The thermal diffusivity ofthe samples was studied for a constant concentration of R6G dye 0.1 g/L. The diffusivities were obtained byusing the thermal lens aberrant model with lasers arranged in the mismatched mode. The characteristic timeconstant of the transient thermal lens was obtained by fitting the theoretical expression, for transient thermallens, to the experimental data.
