Ordinary Raman scattering studies yield information on low-energy excitations of molecules, liquids, and solids. Such information, contained in the frequency shift, k-vector and polarization of the scattered photon, is in general restricted to states which are typically up to 5 × 10-2eV from the ground state of the system under study.

Volume-Enhanced Raman Scattering Detection of Viruses.
Small, 2019Virus detection and analysis are of critical importance in biological fields and medicine. Surface-enhanced Raman scattering (SERS) has shown great promise in small molecule and even single molecule detection, and can provide fingerprint signals of ...

Canadian Journal of Physics, 1986
Observations of Raman scattered light from inhomogeneous laser-produced plasma have shown characteristics quite different from the simple predictions for the stimulated Raman scattering instability. An alternative explanation in terms of enhanced scattering, produced by bursts of hot electrons arising at the quarter-critical or critical surface, is ...

Simultaneous Neutron Scattering and Raman Scattering
Applied Spectroscopy, 2009The capability to make simultaneous neutron and Raman scattering measurements at temperatures between 1.5 and 450 K has been developed. The samples to be investigated are attached to one end of a custom-made center-stick suitable for insertion into a 100 mm-bore cryostat.

This paper briefly reviews some aspects of electronic Raman scattering in simple semiconductors. Emphasis is placed on the strength of the scattering as predicted by the f-sum rule. The mechanism for light scattering by free and bound electrons in a many-valley semiconductor is outlined.

This chapter describes the application of stimulated Raman scattering as a practical method for the generation of tunable, coherent radiation. A brief theoretical discussion of the stimulated Raman effect in the steady state and transient-scattering regimes is presented.

Abstract It is difficult to provide an overview from the physical standpoint of the enormous number of Raman scattering studies performed under pressure. On the other hand, the experimental aspect seems too simple: only a slight modification of the optical scheme is needed to replace a sample by a high-pressure cell, especially by a ...

Anapole-Enhanced Intrinsic Raman Scattering from Silicon Nanodisks
ACS Photonics, 2018Enhancement of inelastic light emission processes through resonant excitation usually correlates with enhanced scattering of the excitation light, as is for example typically the case for surface-enhanced fluorescence and Raman scattering from plasmonic ...

Instantaneous integrated Raman scattering
Applied Optics, 1983Lidar detection of atmospheric molecules using a Raman scattering technique being usually limited by low signals is enhanced by integration of the forward Raman scattered light over a large atmospheric volume. This integral can be measured instantaneously in the presence of a reflector at one edge of the optical path, increasing the SNR by a factor of ...

Mesoscopic and Microscopic Strategies for Engineering Plasmon‐Enhanced Raman Scattering
Advanced Optical Materials, 2018Surface plasmon resonance (SPR) in noble metal nanoparticles and nanostructures offers an efficient means to transport and localize the energy of light into some nanoscale space regions called hot spots, where the electromagnetic field is enhanced by ...
