Abstract
A stimulated Raman scattering of surface electromagnetic waves has been seen experimentally for the first time. In the experiment the picosecond single (transverse)-mode neodimium laser is used. The pump surface electromagnetic wave λL = 1.06 μ) is excited at the silver-benzene interface by the attenuated total reflection method. The signal surface electromagnetic wave is partially radiated into the bulk wave (λs = 1.185 μ), which is detected in the experiment. It is shown experimentally that the stimulated Raman scattering of surface electromagnetic waves does indeed clearly involve a threshold. When the threshold intensity is exceeded by a few percent, the signal increases by three orders of magnitude.
