Hyper-Raman scattering, the nonlinear (two-photon excited) analogue of ordinary Raman scattering, is usually considered to be a weak process that requires high-energy pulsed laser excitation. The sensitivity can be improved greatly by making use of two-photon electronic resonance and/or electromagnetic field enhancement on metal nanoparticle surfaces. Here we demonstrate that hyper-Raman spectra can be obtained from organic dyes on silver colloidal nanoparticle films at laser powers below 1 mW of average power (pulse energies below 2 pJ). These results open the door to exploiting the potential advantages of hyper-Raman scattering for analytical applications.
