%X Supercontinuum generation using continuous-wave pumping
is usually obtained by pumping a suitable fiber with a high-power fiber
laser. Whereas many studies have concentrated in optimizing the dispersion
characteristics of the nonlinear medium (the fiber) used to obtain the
spectral broadening, very few have actually concentrated in optimizing
the pump laser characteristics, and in particular, the dispersion in the
cavity. In this paper we experimentally demonstrate that the fiber laser
cavity dispersion has a strong influence in Raman fiber laser-pumped
continuous-wave supercontinuum generation. We show that anomalous
dispersion in the cavity favors spectral broadening over normal dispersion,
since large, high-contrast intensity noise appears at the output of the laser.
Additionally, we find that there is an optimum value of chromatic dispersion
coefficient to obtain the most efficient broadening.
