Rayleigh scattering in fiber
WebThe amplification effect on stimulated Brillouin scattering (SBS) and Rayleigh scattering in the backward pumped G652 fiber Raman amplifier (FRA) is studied. The pump source is a … WebThe multiple cumulative Rayleigh scattering is the key to the traditional fiber random laser. A double-cavity fiber random laser is fabricated in a capillary tube by a siphon method. Air bubbles are uniformly distributed along the axis of the capillary tube and two incoherent feedbacks to provide optical feedback.
