AB The influence of chromatic dispersion on CW-pumpedsupercontinuum generation in km-long standard fibersis experimentally investigated. We perform our study bymeans of a tunable, high-power fiber ring laser pumpinga dispersion-shifted fiber in the wavelength range ofsmall and medium anomalous dispersion. Our resultsshow that, at low input powers, chromatic dispersionplays a dominant role on nonlinear pump spectralbroadening, giving rise to a broader spectrum whenpumping just above the zero-dispersion wavelength ofthe fiber. At higher input powers, however, the width ofthe generated supercontinuum spectrum is mostly dueto the Raman effect, hence more independent of thevalue of the chromatic dispersion coefficient. We showthat, in this case, the optimum pumping wavelengthsfor supercontinuum generation are not so close to thezero-dispersion wavelength of the fiber as in the previouscase. In these conditions, as the chromatic dispersiongrows we can obtain square-shaped and high-powerdensity spectra, which seem extremely promising forapplications in optical coherence tomography.
