•Brief description on the fiber amplification theoretical models and simulate burst pulse propagating in the fiber amplifier.•Study the variation of rising edge and trailing edge of pulse envelop under different pump scheme.•Found the new exponential varied pump scheme to reshape the pulse envelop.•Employ genetic algorithm to optimize the pulse envelop.
The characteristics of fiber amplifiers of burst pulses envelope during the propagation are comprehensively studied under the conditions of pulsed pump with low repetition rate. The variation of signal envelopes, pump power and upper-level population distribution are discussed in this paper. The impacts of linear varied and exponential varied pump to the raising edge and tailing edge of the output pulses' envelope, are mainly emphasized. Finally, the genetic algorithm is employed to reshape the pulses' envelopes.
