Abstract
In this experiment, unamplified 100-fs CPM laser pulses are employed to couple, optically and resonantly, to the single metal boundary surface-plasmon polaritons (SMSPs) of a 430-Ả thick Ag film. Because the phase velocity of the SMSP is slower than that of a photon of the same energy, direct coupling to a photon field is forbidden. However, using attenuated total internal reflection (ATR) geometry, this momentum matching condition is fulfilled with the aid of a glass prism by adjusting the incident angle of the incoming laser until the photon matches the SMSP dispersion.1 The experiment was performed in a vacuum chamber of 3 × 10-8 Torr with an extraction voltage of 0.5 kV applied to a Cu ring anode.
