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 typic… WebTo draw the Fermi surface in the extended zone scheme, we just need the draw the second Brillouin zone by extending the lines which bisect the basis vectors ~b 1 and ~b 2, and draw the closed star shaped surface.
