Inhibition of stimulated Raman scattering due to the excitation of stimulated Brillouin scattering

Suppression of Stimulated Brillouin Scattering

Near-forward Stimulated Brillouin Scattering

LLE Review, Volume 72 177 In stimulated Brillouin scattering1 (SBS) an incident (pump) light wave is scattered by the electron-density fluctuations associated with an ion-acoustic (sound) wave. This process generates a frequency-upshifted (anti-Stokes) light wave and a frequency-downshifted (Stokes) light wave. For most scattering angles the anti-Stokes wave is driven nonresonantly and can be n...

Stimulated Brillouin Scattering Microscopic Imaging

Two-dimensional stimulated Brillouin scattering microscopy is demonstrated for the first time using low power continuous-wave lasers tunable around 780 nm. Spontaneous Brillouin spectroscopy has much potential for probing viscoelastic properties remotely and non-invasively on a microscopic scale. Nonlinear Brillouin scattering spectroscopy and microscopy may provide a way to tremendously accele...

Comprehensive Theoretical Study on Threshold Power of Stimulated Brillouin Scattering in Single-Mode Fibers

We have investigated and developed a theoretical approach to explore stimulated Brillouin scattering (SBS) phenomena in single mode fiber. SBS happening threshold power condition has been studied in terms of fiber parameters and input pump power. To assess threshold power precisely, the pump depletion effect and fiber loss has been included by employing 1% criterion. The threshold exponential g...

Sideward Stimulated Raman Scattering

The SRS of a short laser pulse is important in the contexts of particle acceleration2 and inertial confinement fusion.3,4 In previous studies of the spatiotemporal evolution of SRS,5–13 the Stokes waves were allowed to pass freely through the pulse boundaries. However, the radial ponderomotive force associated with the pulse can expel plasma from the neighborhood of the pulse axis, in which cas...
