Femtosecond OPO for Surface-Enhanced Raman Scattering (SERS) in Plasmonic Nanocavities

Raman spectroscopy relies on the inelastic scattering of light, where incident photons interact with molecular vibrations, resulting in subtle energy shifts in the scattered light. To overcome this limitation, surface-enhanced Raman scattering (SERS) employs plasmonic nanostructures to amplify the Raman signal. These structures generate localized surface plasmon resonances within nanoscale cavities, intensifying the surrounding electromagnetic field.
