Brillouin Light Scattering in Complex Perovskites

Ferroelectrics, 2004
Results of Brillouin light scattering studies of the behavior of acoustic phonons in PMN, PMT and BMT crystals in a wide temperature range are presented. It is shown that the behavior of a transverse acoustic phonon in PMN crystals is not adequately described by the mode-coupling model.

Brillouin Light Scattering in Plastic Fibers

Asia Communications and Photonics Conference 2014, 2014
We review the unique properties of Brillouin light scattering in plastic fibers at telecom wavelength, and present our recent research progress and future prospects on distributed strain/temperature sensing based on Brillouin scattering in plastic fibers.

Brillouin Components in Light Scattered by Quartz

Nature, 1950
IT was first observed by Gross1 that, when the 4358-A. line of mercury scattered by quartz is examined with a 30-step echelon grating, the line is found to be split up into a doublet, each component being shifted from the centre of the line by 0.18 A. He reported later2 that the line is split up into six components.

Brillouin scattering of light in a liquid crystal

Physics Letters A, 1968
Abstract The stimulated and spontaneous Brillouin scattering of light from cholesteryl 2- (2 ethoxy ethoxy) ethyl carbonate is studied in the temperature range 20° to 60°C. Dispersion of hypersonic sound waves has been observed around the cholesteric to isotropic transition temperature of this compound.

Inelastic light scattering in liquids: Brillouin scattering

Contemporary Physics, 1971
Abstract An account is given of the Brillouin scattering of light from liquids. Different contributions to the Brillouin spectrum are discussed and are shown to depend on liquid properties such as sound velocity, viscosity, thermal conductivity, structural relaxation and concentration effects. The importance of these measurements to liquid-state theory

Brillouin light scattering studies of 2D magnonic crystals

Journal of Physics: Condensed Matter, 2016
Magnonic crystals, materials with periodic modulation of their magnetic properties, represent the magnetic counterpart of photonic, phononic and plasmonic crystals, and have been largely investigated in recent years because of the possibility of using spin waves as a new means for carrying and processing information over a very large frequency ...

Determination of the elastic constants of collagen by Brillouin light scattering

Journal of Molecular Biology, 1979
Abstract The high-frequency elastic properties of rat-tail tendon collagen have been investigated by means of Brillouin (inelastic) light scattering. Longitudinally and transversely polarised elastic waves of frequency about 1010 Hz have been observed propagating at various angles to the fibre axis of stretched, partially dried tendon.

Anti-Stokes scattering of Stokes light and slow light in stimulated Brillouin scattering

Optics and Precision Engineering, 2011
In order to investigate the mechanism of slow-light effect via stimulated Brillouin scattering(SBS),the occurrence of the anti-Stokes scattering of Stokes light and the relationship between the anti-Stokes scattering and the mechanism of slow-light via SBS were researched.It is proved that the Stokes light can also be scattered by Brillouin ultrasounds

Brillouin light scattering study of magnetic dots

physica status solidi (c), 2004
Brillouin light scattering investigation of the thermally activated spin-waves in micrometer-size permalloy square dots shows evidence of a frequency discretization of the surface spin-wave mode which is due to the lateral confinement of the magnetic excitations. The observed frequencies are compared to those derived from the analytical expression in a
