A new technique to produce high power sub-picosecond pulses from a fiber amplifier starting from tenths of picoseconds Fourier transform pulses is presented. We use parabolic pulse shaping of 27ps Fourier transform pulses in order to control nonlinear effects in the fiber amplifier. 63MW, 780fs pulses with 25W average power were obtained, and ways to scale the technique to higher peak powers were identified.
