Induced-modulation-instabilities limit to "fast" light propagation

Summaries of Papers Presented at the Quantum Electronics and Laser Science Conference  
We observe a fantastic spectral broadening of a bichromatic field propagating through a potassium vapor due to a modulation instability, which places severe restrictions on gain-assisted "fast-light" pulse propagation.
