Theoretical Study of Fast Light with Short sech Pulses in Coherent Gain Media
arXiv:quant-ph/0608219 · doi:10.1364/JOSAB.24.000916
Abstract
We investigate theoretically the phenomenon of so-called fast light in an unconventional regime, using pulses sufficiently short that relaxation effects in a gain medium can be ignored completely. We show that previously recognized gain instabilities, including superfluorescence, can be tolerated in achieving a pulse peak advance of one full peak width.
