Surface nanostructuring of nickel by ablation with 350-ps Nd:YAG laser pulses in ethanol has been studied experimentally. The morphology of the nanostructured surface has been examined using a field emission scanning electron microscope. The average lateral size of the surface nanostructures is 30 - 50 nm. The nanostructured surface has been coated with gold using a chemical deposition procedure. The gold-coated substrate has shown surface-enhanced Raman scattering with an enhancement factor of 10{sup 8}. Potential applications of such nanostructured targets are discussed. (nanostructures)
