Abstract: The invention can include an optical pulse source apparatus that includes the nonlinear generation of wavelengths, wherein the optical pulse source can comprise an oscillator for producing optical pulses, the optical pulses having a first wavelength; an optical fiber amplifier for amplifying optical pulses having the first wavelength; a nonlinear optical fiber receiving amplified optical pulses having the first wavelength to nonlinearly produce optical pulses that include wavelengths that are different than the first wavelength; and wherein the optical pulse source is configured so as to be operable to reduce the optical pulse frequency of the nonlinearly produced optical pulses.

Abstract: A method of providing optical supercontinuum pulses can comprise generating optical pump pulses with an optical pump laser, the optical pump pulses having a pump pulse repetition rate; launching optical pump pulses into a nonlinear optical element comprising an optical fiber; generating optical supercontinuum pulses from the optical pump pules via spectral broadening within the optical fiber; selectively providing a plurality of different repetition rates for the optical pump pulses so as to generate optical supercontinuum pulses having different repetition rates; and providing nominally identical spectral broadening of the optical supercontinuum pules having the different repetition rates.
