Frequency shifts in stimulated Raman scattering [PDF]
The nonresonant contributions to the nonlinear susceptibility χ(3) produce a frequency chirp during stimulated Raman scattering. In the case of transient stimulated Raman scattering, the spectrum of the generated Stokes pulse is found at higher ...

Raman gain against a background of non-thermal ion fluctuations in a plasma [PDF]
A complex stimulated Raman scattering event against a background of non-thermal ion acoustic waves in an inhomogeneous plasma is described. We obtain analytic forms for the Raman gain due to a five-wave interaction consisting of conventional three-wave ...

Intersubband electronic Raman scattering in narrow GaAs single quantum wells dominated by single-particle excitations [PDF]
We measured resonant Raman scattering by intersubband electronic excitations in GaAs/AlAs single quantum wells (QWs) with well widths ranging from 8.5 to 18 nm.

Lowering backward Raman and Brillouin scattering in waveguide Raman wavelength converters
Background Liquid filled hollow core fiber Raman wavelength converters are devices enabling to red-shift the wavelength of laser beams delivered by either fixed wavelength or tunable lasers. Most of the reported converters operate in a pulsed regime with

Optimization of electron Raman scattering in double rectangular quantum wells [PDF]
In this work, by using the particle swarm optimization the electron Raman scattering for square double quantum wells is optimized. For this purpose, by combining the particle swarm algorithm together with the numerical solution procedures for equations ...

The influence of phase-modulation on femtosecond time-resolved coherent Raman spectroscopy [PDF]
The influence of phase-modulation on femtosecond time-resolved coherent Raman scattering is investigated theoretically and experimentally. The coherent Raman signal taken as a function of the spectral position shows unexpected temporal oscillations close

Enhanced Raman Scattering by Molecular Nanoaggregates
The formation of a molecular aggregate in a confined, nanodimensioned region of space leads to what might be termed a ‘molecular nanoaggregate’. The present review deals with a theoretical formulation termed ‘aggregation-enhanced Raman scattering’ (AERS),

Observation and analysis of Fano-like lineshapes in the Raman spectra of molecules adsorbed at metal interfaces [PDF]
Surface enhanced Raman spectra from molecules (bipyridyl ethylene) adsorbed on gold dumbells are observed to become increasingly asymmetric (Fano-like) at higher incident light intensity.
