We report on a high power fiber amplifier tandem pumped by an industrial style thin-disk laser. An output power of 1 kW and a very good slope efficiency of 73% have been obtained for a state-of-the-art photonic crystal fiber originally designed for short-pulse amplification. We also compare this result to an experiment, where a power of 2.9 kW could be obtained from a step-index large-mode-area fiber with the same slope efficiency.
