| Research Abstract |
We have observed directly in the ultrashort time-domain, for the first time, that the amplitudes of coherent oscillations are enhanced by the localized electromagnetic fields due to the gold nanostructures This becomes the first step for understanding the dynamics of Surface Enhanced Raman Scattering(SERS), and would provide an important clue for controlling chemical reaction dynamics in solids and/or the surfaces.
