Abstract

Analytic solutions are given for a laser amplifier with swept gain. The inversion pulse moves more slowly than the light pulse, which gives rise to exponential growth under circumstances in which there would otherwise be a gain coefficient that decreases monotonically to zero as the optical pulse evolves. The behavior of the gain coefficient as a function of velocity closely parallels the behavior found in the free-electron laser.
