Stimulated Raman scattering of colored chaotic light
The quantum theory of forward Stokes generation by means of stimulated Raman scattering is extended to the case of a colored (finite-bandwidth) chaotic pump, which has both amplitude and phase fluctuations. In both transient and steady-state limits the mean Stokes intensity is found to be enhanced over that resulting from a coherent pump. In the limit that the chaotic-pump bandwidth becomes lar...
متن کاملGold-silver bimetallic porous nanowires for surface-enhanced Raman scattering.
Highly porous bimetallic nanowires manufactured via a simple galvanic reaction have demonstrated superior activity in surface-enhanced Raman scattering, allowing ultrasensitive chemical detections on isolated porous nanowires in comparison to pristine silver nanowires.
متن کاملWhispering-gallery nanocavity plasmon-enhanced Raman spectroscopy
The synergy effect in nature could enable fantastic improvement of functional properties and associated effects. The detection performance of surface-enhanced Raman scattering (SERS) can be highly strengthened under the cooperation with other factors. Here, greatly-enhanced SERS detection is realized based on rolled-up tubular nano-resonators decorated with silver nanoparticles. The synergy eff...

We investigate femtosecond stimulated Raman scattering (SRS) in H2, D2, HD, and CH4 excited with 300-fsduration pulses at 390-nm wavelength and with as much as 0.1 mJ of energy. We show that the SRSgeneration threshold and conversion efficiency are due to the transient nature of SRS in femtosecond regime. We determine optimal conditions for efficient generation in the broad spectral range 289–7...
