In this paper, We prepared nanoparticles using the Turkevich process. The characterization of gold nanoparticles is carried out using a Scanning Electron Microscope (SEM). Linear optical properties studied by UV-visible Spectroscopy. Investigation of the optical limiting properties (OL) of nanocomposite (AuNPs / Epoxy resin) at different thicknesses (2.5, 9, 10.5, 14.3, 20.5, and 34) μm is performed. The threshold and optical clamping were calculated from optical limiting operation implemented by the Z-scan technique using CW Nd: YAG laser at (532 nm). The samples showed low optical limiting thresholds, which can be demonstrated by the strong absorption of the two photons in these samples. The nanocomposite displays the lowest optical limiting threshold (66 mW) at a thickness (2.5) μm. We notice that the nonlinear light-induced absorption results in an optical limited.
