Electronic Raman scattering in Tl2Ba2CuO6+x: symmetry of the order parameter, oxygen doping effects, and normal state scattering [PDF]
Single crystals of the optimally doped, moderately and strongly overdoped high temperature superconductor Tl2Ba2CuO6+x (Tl-2201) with Tc=80, 56 and 30K, respectively, have been investigated by polarized Raman scattering.

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.

Uncoupled excitons in semiconductor microcavities detected in resonant Raman scattering [PDF]
We present an outgoing resonant Raman-scattering study of a GaAs/AlGaAs based microcavity embedded in a p-i-n junction. The p-i-n junction allows the vertical electric field to be varied, permitting control of exciton-photon detuning and quenching of ...

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.

Sum-frequency ionic Raman scattering
In a recent report sum-frequency excitation of a Raman-active phonon was experimentally demonstrated for the first time. This mechanism is the sibling of impulsive stimulated Raman scattering, in which difference-frequency components of a light field ...

Raman scattering is the inelastic scattering of light by chemical bonds, and can therefore show molecular specificity. It can be used both in pure spectroscopy mode, and in imaging mode. While many applications of Raman spectroscopy and imaging in the biomedical field have been so far demonstrated, the use of this technology for pathology applications ...

A micro-magneto-Raman scattering study of graphene on a bulk graphite substrate
We report on a magneto-Raman scattering study of graphene flakes located on the surface of a bulk graphite substrate. By spatially mapping the Raman scattering response of the surface of bulk graphite with an applied magnetic field, we pinpoint specific ...
