A method of spectrally broadening light pulses includes the steps of providing the light pulses with a laser source, said light pulses having a pulse duration below 1 ps, in-coupling the light pulses into a hollow optical waveguide device, and spectrally broadening the light pulses propagating along the pulse guiding medium by subjecting them to a Raman nonlinearity via excitation of a Raman polarization having a first Raman period, wherein the optical waveguide device subjects the light pulses to anomalous group velocity dispersion which combines with the spectral broadening of the light pulses to result in a Raman-enhanced self-compression of the light pulses, and the light pulses further propagate along the optical waveguide device such that the Raman-enhanced self compression results in a further excitation of a Raman polarization having a second Raman period which is faster than the first Raman period.
