Description We report efficient generation of a broadband supercontinuum (SC) in water upon irradiation by intense, nearinfrared, femtosecond laser pulses. The SC spectra generated when the pump wavelength lies in the anomalous chromatic dispersion region are characterized by largely blueshifted peaks in the visible range. These SC spectral features are rationalized within the framework of a phenomenological self-phase-modulation model, taking into account higher-order group velocity dispersion. Our model provides an intuitive explanation for the relation between the observed pump-wavelength dependence of the blueshifted SC peaks and the anomalous chromatic dispersion.
