Abstract: The nonlinear refraction and nonlinear absorption of dye R2 were studied by the Z-scan technique. Continuous wave (cw) argon ion laser was employed to study the nonlinear response of this dye at several laser powers, solution concentrations and wavelengths. The results established that the R2 displayed a saturable absorption (SA) character and self-defocusing effect. Optical limiting behavior was also studied as a function of concentration and laser wavelength. The limiting threshold values were estimated for the dye solutions at different concentrations and at different laser wavelengths. Our study clearly shows that the R2 dye is excellent nonlinear material with large nonlinear response may provide the basis material for devices in optical applications.
