Abstract
We propose to excite surface plasmon-polaritons using the moving spot of nonlinear polarization created by a laser pulse. Two perspective excitation schemes - with superluminal and subluminal spots - are considered and their efficiencies are compared. These techniques can be used for surface spectroscopy at terahertz frequencies.
