A. Rahman et Jh. Eberly, THEORY OF SHAPE-PRESERVING SHORT PULSES IN INHOMOGENEOUSLY BROADENED 3-LEVEL MEDIA, Physical review. A, 58(2), 1998, pp. 805-808
We introduce an ansatz that permits a treatment of the effects of Dopp
ler broadening in the theory of intense steady-state pulse pairs propa
gating in three-level (Lambda or V) media. We have derived analytic so
lutions for pulse amplitudes, for group and phase velocities, and for
the probability amplitudes of the atoms in the transmission medium. Th
e solutions are different for the Lambda and V cases. [S1050-2947(98)5
