摘要： An atomic object confined in a particular region of an atomic object confinement apparatus is cooled using an S-to-P-to-D EIT cooling operation. A controller associated with the atomic object confinement apparatus controls first and second manipulation sources to respectively provide first and second manipulation signals to the particular region. The first manipulation signal is characterized by a first wavelength corresponding to a transition between an S manifold and a P manifold of a first component of the atomic object and detuned from the S-to-P transition by a first detuning. The second manipulation signal is characterized by a second wavelength corresponding to a transition between the P manifold and a D manifold of the first component and detuned from the P-to-D transition by a second detuning. The first and second detunings selected to establish a dark state associated with a two-photon transition between the S manifold and the D manifold.
