In this work, Au Nps were fabricated by liquid phase pulse laser ablation (PLAL) technique. The experiments were carried out by using the radiation of the pulsed Nd:YAG laser operating at the 1064nm wavelength, 10 ns pulse duration and 1 Hz repetition rate of Au plate immersed in the sodium dodecylsulfate (SDS), The concentration of the sodium dodecylsulfate (SDS) influence on the optical properties and surface morphology Au nanoparticles prepared by pulse laser ablation in liquid. The Ultra violet-Visible show a slightly blue shift was recognized with the increase of the (SDS) concentration and the atomic force microscope shows that the grain size of the obtained NPs are decrease with the increase of the concentration of the sodium dodecylsulfate (SDS)
