For intense beams of light (e.g. laser) traveling in a medium or in a waveguide, such as an optical fiber, the variations in the electric field of the beam itself may induce acoustic vibrations in the medium via electrostriction or radiation pressure. The beam may display Brillouin scattering as a result of those vibrations, usually in the direction opposite the incoming beam, a phenomenon known as stimulated Brillouin scattering (SBS). For liquids and gases, the frequency shifts typica… WebSBS is the process by which high intensity light generates a backward traveling Stokes wave; thus limiting the forward traveling power. In an active fiber, this process is particularly worrisome as the backwards traveling wave can cause pulsations; leading to the destruction of components in the fiber amplifier. Web2.1.4.2 Brillouin Fiber Amplifiers . The optical gain in SBS process can be utilized in amplification of weak signal provided the frequency shift of weak signal from pump frequency is equal to Brillouin shift.
