We report the generation of high-energy high-peak power pulses in an all-normal dispersion fiber laser featuring large-mode-area photonic crystal fibers. The self-starting chirped-pulse fiber oscillator delivers $11\mathrm{W}$ of average power at $15.5\mathrm{MHz}$ repetition rate, resulting in $710\mathrm{nJ}$ of pulse energy. The output pulses are dechirped outside the cavity from $7\mathrm{ps}$ to nearly transform-limited duration of $300\mathrm{fs}$ , leading to pulse peak powers as high as $1.9\mathrm{MW}$ . Numerical simulations reveal that pulse shaping is dominated by the amplitude modulation and spectral filtering provided by a resonant semiconductor saturable absorber.
