摘要：

We investigate quantitatively the local coupling efficiency of a strongly focused laser beam to surface plasmon polaritons on a gold thin film. The coupling is mediated by gold ridges with nanoscale cross section. The coupling efficiency is determined by measuring the leakage radiation emitted by the surface plasmon polaritons into the glass substrate supporting the thin film.
