Abstract: Periodic surface structures on aluminium are produced by femtosecond laser pulses for efficient excitation of surface electromagnetic waves using a strong objective (NA = 0.5). The local electromagnetic field enhancement on the structures is measured using the technique of surface-enhanced Raman scattering from pyridine molecules.

Keywords: femtosecond laser pulses, periodic surface nano- and microstructures, local field enhancement, surface-enhanced Raman scattering (SERS).
