<![CDATA[In this study, the investigation of the nonlinear and optical properties of nanoparticles (AgNPs) in distilled water with gold nanoparticles (AuNps) was investigated. The non-linear absorption coefficient of nanotubes was measured by Z-scan. Nanonuclear AuNps with AgNPs under exposure to nano-laser pulses at 532 nm as well as 405 nm and 650 nm. The results showed that nonlinear diffusion can increase the performance of the optical marker. A theoretical analysis is proposed Investigate non-linear behavior observed from AgNPs with AuNPs. Shows that the dispersion of non-linear light occurs at high intensity because of the inverse refractive mismatch between silver nanoparticles with gold and water. TheZ- scan experimental data were provided with the proposed theoretical model, allowing the extraction of nonlinear absorption coefficients and linear and nonlinear propagation coefficients for AgNP suspension with AuNPs.]]>
