Abstract
Pulsed fiber lasers that amplify seed laser pulses include pump laser drivers that produce simmer currents during periods in which the seed pulse is suspended, and forward currents associated with steady state pulse amplification. By suitable selection of simmer currents, initiation of a series of seed pulses produces pulse-to-pulse output powers with suitable power variation.
