Abstract
We consider propagation of a pulse carrying optical information in a resonant medium of
twolevel atoms and revisit the concept of the group velocity. We obtain conditions when this concept
may be used and show that in a population inverted medium the possible superluminal propagation
may result in advance times much shorter than the pulse duration because of lethargic amplification
following from the complete exact solution of the problem.
