Controlling the Raman response of inhomogeneously distributed multiple vibrational modes with optimally shaped light fields.
We demonstrate that Raman-effect-assisted transformations of ultrashort pulses in materials with inhomogeneously distributed multiple vibrational modes can be tailored by optimally ordered pulse sequences and appropriate optical sampling. This suggests attractive strategies for a synthesis of few-cycle pulses, enhanced spectral transformation of light fields, and pulse shaping in silica fibers and other materials with multiple Raman modes.
