Thermal Transport Properties of W2TMB2 Solid Solutions (TM = Fe, Co, Ni)
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Thermal transport properties of W2TMB2 (TM: Fe, Co, Ni) and their solid solutions, as well as electron backscatter diffraction measurements, show interesting particularities depending on the TM type and content. In this work, thermal transport properties of W2FexCo1‐xB2, W2FexNi1-xCoB2, and W2NixCo1‐xB2 (x: 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) were ...

Brillouin Scattering from Gels
MRS Proceedings, 1991AbstractWe have investigated the question of heterogeneity in gels using Brillouin scattering, depolarized Rayleigh scattering and dynamic light scattering measurements on methylmethacrylate (MMA) gels crosslinked with varying amount of ethylene-dimethacrylate (EDMA).

Coherent Rayleigh-Brillouin Scattering
Physical Review Letters, 2002Coherent Rayleigh-Brillouin scattering in gases has been studied experimentally for the first time in the kinetic regime and shown to give line shapes that differ significantly from the spontaneous Rayleigh-Brillouin scattering. A kinetic model was developed to obtain an analytic solution of the line shape for monatomic gases, and good agreement with ...

Multikilohertz stimulated Brillouin scattering
Optics Letters, 1994We report, for the first time to our knowledge, multikilohertz stimulated-Brillouin-scattering phase conjugation of copper-vapor laser radiation. The small wavelength shift associated with the Stokes radiation is shown to permit double-pass aberration correction of the copper-vapor laser, avoiding the postlasing absorption.

Stimulated Brillouin Scattering
Applied Optics, 1969Stimulated Brillotuin scattering, the efficient scattering of light from parametrically amplified therma acoustic waves, has found many valuable uses since its initial observation and identification. Among these uses are included the measurement of hypersonic velocities and absorption in the gigaherz frequency range, laser frequency shifting, laser Q ...

Abstract Brillouin scattering is the inelastic interaction of light with acoustic phonons which results in a shift in the frequency of scattered radiation. This effect is similar to Raman scattering, but information is obtained abont acoustic branches of the phonon spectrum.

Neutron News, 1990
Abstract For several years, an international group of scientists has been developing instrumentation and gathering experience regarding neutron Brillouin scattering. The requirements are neutrons of relatively high energy, small scattering angles, and high resolution in order to obtain data at small momentum transfer and high energy transfer.

Stimulated Brillouin Scattering
2022Abstract Stimulated Brillouin scattering (SBS) is based on a gain mechanism provided by the pump light reflection from the induced hypersonic acoustic Bragg grating in a continuous net optical medium. The mathematic formulation of SBS generation is based on the solutions of the coupled wave equations that describe the pump field-induced ...

Brillouin Scattering in Sodium Nitrite
Journal of the Physical Society of Japan, 1974The Brillouin scattering spectra in NaNO 2 have been studied using a Fabry-Perot interferometer. The observed Brillouin shifts for eighteen acoustic phonons in nine scattering geometries have been assigned to specific modes of vibration. The determined values of nine elastic constants in units of 10 10 dyn/cm 2 are C 11 =31.7, C 22 =58.2, C 33 =66.0, C
