Second-harmonic generation from plasmon polariton excitation on silver diffraction gratings: Comparisons of theory and experiment
We present a comparison between experimental and theoretical results for the diffraction efficiencies of the secondharmonic light produced in the orders of silver diffraction gratings. The gratings considered are sinusoidal, have depths of a few nanometers, and can produce significant surface plasmo...
