The linear and nonlinear optical properties represented by nonlinear refractive index and nonlinear absorption coefficient were determined using a highly sensitive method known as Z-scan technique. Z-scan experiment was performed using Nd-YAG1064) nm( and Nd-YVO4 laser in two parts532) nm). The first part has been done using a closed aperture placed in front of the detector to measure the nonlinear refractive index at two wavelengths. The second part was done using an open aperture to measure the nonlinear absorption coefficient at two wavelengths.
