Recent Progress in Distributed Brillouin Sensors Based on Few-Mode Optical Fibers
Brillouin scattering is a dominant inelastic scattering observed in optical fibers, where the energy and momentum transfer between photons and acoustic phonons takes place.

The measurement accuracy of Brillouin scattering spectra is crucial for ocean remote sensing by Brillouin scattering lidar. Due to the limited resolution of ICCD cameras, the traditional processing methods remain at the pixel or partial sub-pixel level ...

Investigation of Brillouin scattering parameters in single mode optical fibers
The interrogation scheme for fiber optic sensor based on Brillouin scattering is represented. The application of stimulated Brillouin scattering signal formed in etalon optical fiber as reference source realized is proposed.

Cascaded forward Brillouin lasing in a chalcogenide whispering gallery mode microresonator
We report the first observation of cascaded forward stimulated Brillouin scattering in a microresonator platform. We have demonstrated 25 orders of intramodal Stokes beams separated by a Brillouin shift of 34.5 MHz at a sub-milliwatt threshold at 1550 nm.

We measure the spectrum of coherent Brillouin scattering (CBS) in a gas as a function of time and observe for the first time additional spectral sidebands and line shape narrowing of the Brillouin peak. We find that both effects result from the interference of the density modulation induced by the moving dipole force of the pump beams with the acoustic

Brillouin scattering of phonons in complex materials
Initially, the theory of propagation of long-wavelength acoustic phonons and Brillouin scattering of laser light in condensed matter is concisely summarized. Then, the case of two relevant classes of complex materials in which Brillouin scattering can be

Hybrid Ytterbium/Brillouin Gain Assisted Partial Mode Locking in Yb-Doped Fiber Laser
We have demonstrated experimentally and theoretically that the hybrid ytterbium/Brillouin gain can contribute to partial mode locking in the high-loss ytterbium-doped fiber laser.
