Abstract :
We propose to launch terahertz surface plasmons on corrugated metal surfaces by ultrashort laser pulses. The plasmons are emitted by nonlinear polarization created by the pulse in a strip of electro-optic medium deposited on the surface. The technique can be used for terahertz surface spectroscopy.
