Brillouin Light Scattering: Applications in Biomedical Sciences [PDF]

open access: yesChemical Reviews, 2019
Brillouin spectroscopy and imaging are emerging techniques in analytical science, biophotonics and biomedicine. They are based on Brillouin light scattering from acoustic waves or phonons in the GHz range, providing a nondestructive contactless probe of the mechanics on a micro-scale.

Brillouin light scattering of spin waves inaccessible with free-space light [PDF]

open access: yesPhysical Review Research, 2020
Microfocus Brillouin light scattering is a powerful technique for the spectroscopic and spatial characterization of elementary excitations in materials. However, the small momentum of light limits the accessible excitations to the center of the Brillouin

Brillouin Light Scattering from Magnetic Excitations. [PDF]

open access: yesMaterials (Basel), 2023
Brillouin light scattering (BLS) has been established as a standard technique to study thermally excited sound waves with frequencies up to ~100 GHz in transparent materials. In BLS experiments, one usually uses a Fabry–Pérot interferometer (FPI) as a spectrometer.

Fano meets Stokes: Four-order-of-magnitude enhancement of asymmetric Brillouin light scattering spectra [PDF]

open access: yesPhotoacoustics, 2023
Observation of Fano resonances in various physical phenomena is usually ascribed to the coupling of discrete states with background continuum, as it has already been reported for various physical phenomena.

Shear Brillouin light scattering microscope. [PDF]

open access: yesOpt Express, 2016
Brillouin spectroscopy has been used to characterize shear acoustic phonons in materials. However, conventional instruments had slow acquisition times over 10 min per 1 mW of input optical power, and they required two objective lenses to form a 90° scattering geometry necessary for polarization coupling by shear phonons. Here, we demonstrate a confocal

Magnon laser based on Brillouin light scattering [PDF]

open access: yesOptics Letters, 2020
An analogous laser action of magnons has become a subject of interest, and it is crucial for the study of nonlinear magnons spintronics. In this Letter, we demonstrate the magnon laser behavior based on Brillouin light scattering in a ferrimagnetic insulator sphere, which supports optical whispering gallery modes and magnon resonances. We show that the

Characterization of the Microstructure of Sr0.75Ba0.25Nb2O6 Thin Films by Brillouin Light Scattering [PDF]

open access: yesNanomaterials
Strontium-barium niobate (SrxBa(1−x)Nb2O6) films can be considered as a promising material for microwave applications due to high dielectric nonlinearity and relatively low losses. Since strontium-barium niobate has a disordered structure that determines

The hidden limit in light: intrinsic noise reshaping Brillouin metrology [PDF]

open access: yesLight: Science & Applications
Spontaneous Brillouin scattering is widely used to probe the mechanical and thermal state of matter, yet it has been assumed to be intrinsically stable.

Coherent states in brillouin light scattering

open access: yesArchives of Acoustics, 2001
The present article describes inelastic light scattering or the theory of photon acoustic- phonon interactions to which the coherent state formalism can be applied; it belongs partly to quantum acoustics.
