    • Abstract
  • To study effect of pump power deployment on bi-directional pumping fibre Raman amplifiers(FRA), the gain, gain saturation and power conversion efficiency under different pump power deployment were calculated based on the known coupling equations. The simulation results show that the gain, gain saturation and power conversion efficiency are all between the values of forward-pumped and backward-pumped FRAs and they increase when forward pump power is larger. The phenomenon becomes evident with all the pump power and initial signal power increases. The conclusion gives some advice for the work of FRA and fibre laser.
