Abstract
In Chap. 7 we showed that in the weak probe limit, where we assume all of the population remains in the ground state, the group index of a dense Rb atomic vapour can be very large. In this chapter instead of only weakly probing the ground-state medium, we drive significant population into the excited state with a second pump laser, and explore the time-response of the system to this strong perturbation.
