We design a narrow linewidth pulsed core-pumped double-cladding large mode area ytterbium-doped fiber amplifier (LMA-YDFA) operating at 1016 nm, and experimentally investigate the effects of different input signal laser power, YDF length, pump power and pumping mode on the output characteristics of the amplifier. The results show that the core pumped LMA-YDFA is feasible in power amplification, gain fiber shortening and ASE suppression. We compare the core pumped LMA-YDFA with the single mode ytterbium-doped fiber amplifier (SM-YDFA). The latter has the self-phase modulation (SPM) that the former does not have. The results show that the core pumped LMA-YDFA can better suppress the nonlinear effect and spectral broadening of the narrow linewidth pulse laser in the amplification process.
