Abstract: | We report on the experimental observation of optical phase conjugation using surface plasma waves in two different configurations: one involving four surface plasma waves and the other one involving two surface pump waves and bulk probe and conjugate waves. The major nonlinear contribution comes from heating of the metal film. In a related experiment, we have also observed the coupling of a bulk probe wave to the corresponding surface wave through the grating created by two counter-propagating surface plasma waves. In this case, we could observe the creation of surface acoustical waves. |
