Brillouin Light Scattering: Applications in Biomedical Sciences. [PDF]
Chem Rev, 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 from Magnetic Excitations. [PDF]
Materials (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]
Photoacoustics, 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]
Opt 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

Characterization of the Microstructure of Sr0.75Ba0.25Nb2O6 Thin Films by Brillouin Light Scattering [PDF]
NanomaterialsStrontium-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]
Light: Science & ApplicationsSpontaneous 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
Archives 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.

Light bullet generation via stimulated Brillouin scattering
APL PhotonicsWe propose an all-optical approach to generating space–time wave packets in a multimode slab waveguide via the multilevel interband stimulated Brillouin scattering process. Two pump sources and a single-mode signal are fed into the waveguide.

Magnon laser based on Brillouin light scattering [PDF]
Optics 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
