### Abstract

Summary form only given. We have demonstrated that the second zero in the GVD of a narrow waist tapered fiber can be used to generate a continuum at wavelengths comparable to and longer than the material zero-dispersion wavelength (ZDW). Unamplified femtosecond-pulses from a Cr:forsterite oscillator underwent in excess of 15-times spectral broadening. These results confirm the use of the second zero in the GVD of a tapered fiber as an effective medium for the generation of broadband light at wavelengths longer than the material ZDW.
