Claim:
1. A super-continuum system comprising: a mode-locked fiber laser with an optical bandwidth corresponding to a transform limited pulse duration of less than 1 ps and a pulse repetition rate of more than 1 MHz configured to output a pulse having a center wavelength; a first nonlinear waveguide configured to shift the wavelength of the pulse from the mode-locked fiber laser; a first fiber amplifier of at least one stage configured to amplify the output from the first nonlinear waveguide and further configured to output femtosecond pulses by using the interplay between the dispersion and nonlinearity in the first fiber amplifier; and a second nonlinear waveguide with a zero-dispersion point that is close to the center wavelength of the pulses exiting the first fiber amplifier configured to spectrally broaden the output from the first fiber amplifier by self-phase modulation.
