Abstract

This research is a study of the nonlinear optical properties for liquid and solid sample (dye doped polymer) at different concentration in Chloroform solvent by using a high sensitive method known as EZ-Scan technique. EZ-scan experiment was performed using Nd-YAG (SHG) CW laser at 532[nm] in two parts. The first part by using a disk placed in front of the detector to measure the nonlinear refractive index and in the second part removing the disk (open aperture) to measure the nonlinear absorption coefficient and then to measure third order susceptibility. The results suggest that the solid samples were appeared clearer than liquid samples since the nonlinear refractive index is found to be of the order of 10-11[cm2/mw]. The magnitude of nonlinear susceptibility is of the order of 10-4[cm/watt]. The nonlinear absorption coefficient is of the order of 10-4[cm/mw].
