We report on the generation of high-average-power and high-peak-power ultrashort pulses from a mode-locked fiber laser operating in the all-normal-dispersion regime. As gain medium, a large-mode-area ytterbium-doped large-pitch photonic-crystal fiber is used. The self-starting fiber laser delivers of average power at repetition rate, resulting in of pulse energy. The laser produces positively chirped output pulses, which are compressed down to sub-, leading to pulse peak powers as high as .
