Abstract
Using the numerical solution of the Maxwell–Bloch equations, we study the interaction of short light pulses with resonant amplifying media. We consider pulses of various shapes – with Gaussian, rectangular, and exponential envelopes, the latter of which has recently attracted increased attention due to its potential for implementing new effects such as virtual absorption. We show that by choosing the shape and duration of the incident pulses, we can control the intensity and time of the amplified radiation generation, as well as the population dynamics of the medium levels.
