1. A chirped pulse amplification system, comprising:

  • a pulse generator, configured to generate a laser pulse;

    a pulse stretcher, configured to generate a stretched pulse from the laser pulse by dispersing it temporally as a function of wavelength;

    a pulse amplifier, configured to generate an amplified pulse from the stretched pulse; and

    a pulse compressor comprising a Bragg fiber, configured to generate a compressed pulse from the amplified pulse, wherein the pulse stretcher or the pulse compressor is tunable to control a total group velocity dispersion of the chirped pulsed amplification system.
