Structural dispersion and nonlinearity management of multicomponent-glass photonic-crystal fibers is shown to allow wavelength-tunable frequency shifting and white-light spectral transformation of femtosecond Cr:forsterite laser pulses. Launching 200 fs pulses of 1.25 μm Cr:forsterite laser radiation into such dispersion-managed soft-glass photonic-crystal fibers in the regime of anomalous dispersion, we demonstrate spectrally tailored supercontinuum generation and frequency upshifting, yielding isolated spectral components with central wavelengths ranging from 400 to 900 nm.
