On the basis of measurements and theoretical analysis, linear nonlinear optical properties on Ag:Bi2O3 composite films with different Ag concentrations were investigated. The relationship between surface plasmon resonance (SPR) characterized by UV-VIS-NIR spectroscopy, dependence third-order susceptibility was investigated picosecond Z-scan technique excitation wavelength (532nm 1064nm). analysis these carried out using theories localized field enhancement respectively. From experimental results, susceptibilities χ(3) concentration shown. With around 35％ at 532nm near (560nm—622nm), showed a maximum value 2.4×10-9 esu.
