The intensities of the higher frequency anti-Stokes components of resonantly pumped Raman scattering are observed to be greatly enhanced as a result of minimizing dispersion when focusing into a hollow fiber, as compared to their intensities at higher pressures. As well, the significant spectral broadening of these Raman orders in the absence of any such broadening on the pump beams suggests the synthesis of a short temporal structure as a result of a the decreased dispersion.
