Abstract

We show that enhanced compression of short pulses can be obtained by propagating them through a two-level atom medium characterized by an inhomogeneously broadened atomic line with a spectral hole. The area theorem remains valid, and consequently there is a slowing down of the pulse area compared with that observed in the analogous case of an amplifier without any hole. On the other hand, there are relative increases in the pulse time width and its energy content. Among the special cases, an inhomogeneous atomic line with a zero on the carrier frequency resonance produces a stable pulse with a zero area.
