Abstract. The capabilities of laser ablation in liquids for fabrication of metallic and composite nanoparticles were analyzed. The properties of Ag, Au and Cu as well as bimetallic Ag-Cu and Ag-Au nanoparticles synthesized in different liquids (water, acetone, ethanol) were examined. The results obtained showed both the mean size of the nanoparticles and their stability could be controlled by proper selection of the parameters of laser ablation such as temporal delays between pulses, laser fluence and a sort of liquid used. The optimal conditions favoring the formation of nanoparticles with a desired structure were found.
