Conjugated organic molecules are the best candidates for the study of nonlinear optical properties mainly due to the differences in conjugation length. We used the Z-Scan technique in the femtosecond and millisecond time scales to investigate the nonlinear properties of Sudan I derivatives, associated to eletronic and thermal mechanisms, respectively. These mechanisms can be studied by measuring both the nonlinear refractive index n2 and absorption coefficient �. Typical Z-Scan curves for Sudan I (Figure 1) and derivatives are similar.
