1. A fiber chirped pulse amplification system, comprising;

  • a seed source generating optical pulses;

    a pulse stretcher for temporally stretching pulses from said seed source thereby generating chirped optical pulses;

    a non-linear amplifier disposed downstream from said pulse stretcher and arranged to receive and amplify chirped optical pulses, said non-linear amplifier configured to generate substantial self-phase modulation and corresponding non-linear phase delay of pulses propagating therein, wherein a spectrum at the output of said non-linear amplifier is characterized by having increased amplitude modulation with an increase in pulse energy; and

    a pulse compressor disposed downstream from said non-linear amplifier and arranged to receive amplified chirped pulses and to temporally compress said amplified chirped pulses,wherein said stretched pulses amplified in said amplifier are subjected to said substantial level of self-phase modulation, and said substantial level of self-phase modulation provides a level of third-order dispersion that at least partially compensates for the level of third-order dispersion from said pulse stretcher and said pulse compressor.
