The generation of the sum frequency of visible (0.5235 mu m) and IP (1
0 mu m) radiation on smooth and corrugated silver surfaces is investig
ated. The sum-frequency signal obtained with a visible-range surface p
lasmon-polariton excited on a corrugated silver-air interface is found
to be more than four orders of magnitude stronger than the signal fro
m a smooth silver surface. (C) 1997 American Institute of Physics. [S0
