We report on the generation of 265 nJ ultra-short pulses from a mode-locked Ytterbium-doped short-length large-mode-area fiber laser operating in the dispersion compensation free regime. The self-starting oscillator emits 2.7 W of average power at a pulse repetition rate of 10.18 MHz. The pulses have been compressed down to 400 fs, corresponding to 500 kW peak power. Numerical simulations confirm the stable solution and reveal the mechanisms for self-consistent intracavity pulse evolution. The pulse energy is one order of magnitude higher than so far reported for fiber oscillators in the 1 um wavelength region. To our knowledge this is the first time that mode-locked fiber oscillators can compete in terms of pulse energy and peak power with most advanced bulk solid-state femtosecond lasers.
