1. A method of producing an ultrashort high-energy optical pulse, comprising:

  • generating a chirped optical signal;

    amplifying the chirped optical signal; and

    compressing the amplified optical signal to an ultrashort duration optical pulse having a duration of less than 10 picoseconds, wherein at least some of the compression is performed by introducing the optical signal into a Bragg-fiber waveguide, the waveguide comprising an inner core region in which the optical signal is confined, and a plurality of substantially concentric annular regions of differing refractive indices surrounding the inner core region.
