The quest for materials exhibiting high nonlinear refraction and absorption are required for photonic device application. In this paper we report a simplified Z-scan technique, to study the optical nonlinearity of the dye Bromocresol Purple (cas 115-40-2) in methanol and ethanol for different concentration and dye doped polymer film at the wavelength 532 nm of Nd:YAG laser. The experimental results show that the investigated organic dye molecule exhibits saturation absorption and negative nonlinearity. The nonlinear absorption co-efficient and the nonlinear refractive index were measured for the dye doped film, and for dye in methanol and ethanol at the concentration of 0.03 mM and 0.05 mM. The measured third order susceptibility was found to be of the order of 10−6 e.s.u. in both solid and liquid medium. The result shows that the dye has potential applications in nonlinear optics.
