Coherent backscattering of Raman light
, 2017 Coherent backscattering of light is observed when electromagnetic waves undergo multiple scattering within a disordered optical medium. So far, coherent backscattering of light has been studied extensively for elastic (or Rayleigh) light scattering.

Rayleigh backscattering lasing control based on Raman amplification
IET Optoelectronics, 2012 In this work, a method to induce controlled Raman gain profile in the far L- and U-bands using only an E-band Raman pump with co-located passive elements in C-band is presented and experimentally assessed. This process gains control of C-band spontaneous Rayleigh backscattering (RB) by means of one set of fibre Bragg gratings (FBG), providing resonant ...
