    • In the MK protocol one prevents the control field from interacting with the populated level, not only to ensure uniform illumination of the medium, but also to avoid excitation to the upper level that would entail amplification and spontaneous emission noise. This cannot occur in the present protocol.

    • This connection between the inhomogeneous phase shift and spatial position is unique to the Doppler effect. The phase shift is connected simply to the distance travelled by the atoms. As a consequence, even a short laser pulse can result in an accumulated Doppler phase shift for the atoms. This rather paradoxical feature does not occur when the inhomogeneous broadening is caused by position-dependent energy level shifts of stationary atoms, as in a solid.
