Cavity and random ultralong fibre laser amplification in BOTDAs: A comparison  
Description:
The predicted performance of BOTDA sensors, assisted by Raman amplification provided through either cavity or bi-pumped mirrorless random ultralong laser schemes, is compared, showing that, although the latter are less affected by RIN transfer for sensing lengths above 100 km, they also require much higher pump powers and suffer more from SPM-induced broadening of the Brillouin pulsed pump. © 2014 Astro Ltd.
