Coherent, optically dressed media composed of two-level atomic systems without inversion symmetry make optically tunable sources of radiation in the GHz-THz domain. Here, full propagation dynamics of such low-frequency impulses is investigated to eventually formulate conditions for stable impulse buildup.
