摘要：

Surface-enhanced coherent anti-Stokes Raman scattering has been observed on colloidal silver surface from benzene, the mixture of benzene and N,N-dimethylformamide, toluene, and chlorobenzene. Silver colloids which were prepared in organic solvent N,N-dimethylformamide were used as an enhancement medium. The scattered CARS light was collected at right angles with respect to the exciting pump and Stokes laser beams. It was found that not only is the CARS signal significantly enhanced but the signal-to-noise ratio is also improved after addition of the silver sol. An excitation profile study shows a maximum enhancement for the benzene-silver sol system located at about 500 nm pump laser wavelength. This is in good accord with the surface plasmon resonance of the system.
