Abstract
Combination of the plasmonic local-field enhancement and the ultrashort optical pulses in the midinfrared
range promises novel applications of surface-enhanced nonlinear vibrational spectroscopy and
strong-field light-matter interactions. In this paper, we describe fundamental differences between
plasmonics in mid-infrared and at shorter wavelengths and investigate temporal and spectral properties
of local-field enhancement achieved with metal nanostructures at mid-infrared frequencies.
