Third-order nonlinear optical properties of cover glass coated with different metal films are studied by using a focused pulse laser (λ=532 nm, pulse width 0.7ns, repetition rate 15.79kHz) with a Z-scan system. The results of open-aperture mode Z-scan shows high transmittance in the AgOx sample. The enhanced third-order nonlinear coefficients were examined by close-aperture mode Z-scan. The plasmon excitation and thermal relaxation were discussed for experimental results.
