Suppression of stimulated Brillouin scattering in optical fibers using a linearly chirped diode laser [PDF]
, 2012 The output of high power fiber amplifiers is typically limited by stimulated Brillouin scattering (SBS). An analysis of SBS with a chirped pump laser indicates that a chirp of 2.5 × 10^(15) Hz/s could raise, by an order of magnitude, the SBS threshold ...
