Fast Light in Fully Coherent Gain Media
arXiv:quant-ph/0604159 · doi:10.1364/OL.31.002921
Abstract
We analyze the propagation of fast-light pulses through a finite-length resonant gain medium both analytically and numerically. We find that intrinsic instabilities can be avoided in attaining a substantial peak advance with an ultra-short rather than a long or adiabatic probe.
