Abstract
Observations of a frequency-shifted coherent conical emission from systems pumped by an intense optical field that is nearly resonant with a one-photon transition1 have made it clear that propagation effects can play a major role in determining the spectrum as well as the spatial characteristics of the transmitted pulse. Proposed theories of conical emission stress the importance of transverse effects leading to four-wave mixing1 or spatial self-phase modulation.2 We report computer results on laser propagation in a two-level system and demonstrate that spatial structure, including conical emission, can result from temporal propagation effects.
