Abstract: (2248 Views)
In this paper, the nonlinear optical properties of copper nanostructure thin-films, including nonlinear refractive index and absorption coefficient, have been investigated. The samples were prepared in two thicknesses of 25 nm and 130 nm by Resistance Thermal Evaporation(RTE) deposition method, also the Z- Scan technique with continuous diode laser at 532 nm was used to obtain nonlinear optical properties. The results of this study shows that the sing of nonlinear refractive index changes with increasing thickness of the films, and the nonlinear absorption coefficient decreases.
Keywords: Copper nanostructure thin-films, Nonlinear refractive index and absorption coefficient, Resistance Thermal Evaporation(RTE) deposition
