In this paper zinc oxide sheets are grown on a FTO substrate using electrochemical method. The nonlinear optical coefficients of these sheets are determined using the z-scan technique. In this method, a cw Nd-YAG laser with wavelength of 532 nm is applied as the radiation source. Our experimental results indicate that the ZnO sheets have positive nonlinear refractive index and exhibit the nonlinear self-focusing phenomenon. Furthermore, the z-scan results reveal that ZnO sheets grown in this paper possess saturated absorption. Finally, the third order nonlinear susceptibility is obtained for ZnO sheets by using the measured nonlinear refractive index and nonlinear absorption coefficient.
