Abstract

The spatial self-phase modulation effect was exploited to study the nonlinear optical parameters of the acid blue 29 dye solutions. The acid blue 29 dye was used as samples and it was dissolved in four different alcohols. The trend in these experiments to investigate the influence of solvent structure on the formation and the temporal evolution of the far field self-diffraction ring patterns of the Gaussian laser beam passing through the studied samples. The nonlinear refractive index (n2), birefringence (Δn2) and thermo-optic coefficient [dn/dT] were determined from the obtained self-diffraction ring patterns. Our results have indicated that the difference between the numbers of diffraction rings is attributed to the type of the solvents and to the incident laser beam intensity.
