100W fully-fiberised ytterbium doped master oscillator power amplifier incorporating adaptive pulse shaping [PDF]
, 2009 We report a pulsed, fully-fiberised, Yb-doped MOPA with a maximum average output power of 100W. Adaptive pulse shaping was incorporated to reduce the impact of nonlinearities, delivering 2mJ flat-topped pulses with 20kW peak ...

Suppression of Transient Gain Excursions in EDFA’s [PDF]
, 2006 In this paper a comparative study of two pump control schemes for suppressing transient gain excursions in EDFA’s is presented. The first control scheme is based on the traditional feedforward/feedback control, while the second scheme is new and uses multiplication to combine the feedforward and feedback blocks.
