In this study, nanostructure thin films of Cu and Zn are prepared bypulsed laser deposition (PLD) method and their nonlinear absorptioncoefficient and refractive index are studied by z-scan. The details ofPLD parameters are presented for both metals of Cu and Zn. A cwlaser beam at 532 nm and the output power of 130 mW was used in zscanexperiment. The sign and the magnitude of nonlinear absorptioncoefficient and refractive index of the nanostructure thin films aremeasured by z-scan curves.
