1. A method for generating high power ultrashort-pulses using a chirped pulse fiber amplifier, comprising the steps of:

  • chirping an input pulse to be amplified, thereby creating a chirped pulse that is broadened in time;

    modifying said chirped pulse by increasing the power of said pulse with a fiber amplifier to induce a nonlinear phase shift in said pulse which substantiality changes a shape of a power spectrum of said pulse; and

    dechirping said pulse to generate a narrowed output pulse.
