MATLAB-based experimental analysis of optical limiting properties of Cu/Ag mixture nanoparticles

The evolution of nanoclusters in sequentially ion-implanted Cu/Ag into silica glasses has been studied. Third-order nonlinear optical properties of the nanoclusters were measured at 1064 nm excitations using the Z-scan technique. Results of the investigation of nonlinear refraction by the off-axis Z-scan configuration were presented and the mechanisms responsible for the nonlinear response were discussed. The innovative point of this paper is that we carried out curve fitting analysis, which is based on MATLAB features, for Cu/Ag optical limiting experiment. Our results showed that Cu/Ag mixture nanoclusters have refractive optical limiting effect at 1064 nm.
