Generation of noise-like pulses with a 920 fs pedestal in a nonlinear Yb-doped fiber amplifier.

open access: yesOptics Express, 2019
We demonstrate the compression of noise-like pulses in an Yb-doped fiber master-oscillator power-amplifier (MOPA). The seed source of the MOPA is an NPR mode locked fiber laser delivering 5.94-ps dissipative soliton pulses with a repetition rate of 37.48
