absorption profile. EIT cooling is realized when , such that the carrier transition lies on the dark resonance of the Fano-like feature, where is used to label the quantized motional state of the atom. The Rabi frequency of the coupling laser is chosen such that the "red" sideband lies on the narrow maximum of the Fano-like feature. Conversely the "blue" sideband lies in a region of low excitation probability, as shown in the figure below. Due to the large ratio of the excitation probabilities, the cooling limit is lowered in comparison to doppler or sideband cooling (assuming the same cooling rate).
