Paper Abstract

The predicted performance of BOTDA sensors assisted by Raman amplification provided through either cavity or laterally-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 pulsed Brillouin pump.
