“…We also note that for cooling in dimensions of 2 or more, modulation of the magnetic field and polarization may not be necessary to remix hyperfine states, simplifying the magnetic coil design. Type II atomic MOTs operate with similar level structures, and remixing occurs from lasers propagating in orthogonal directions (29).…”

“…The dark state population must be rapidly returned to bright states to allow significant cooling and confinement. Typically, MOTs based on type-II structures are observed to yield weaker confining forces and higher temperatures than those using a type-I structure [18,19].…”

“…The MOT is vapor-loaded from a hot neutral Na source. The atoms can be trapped using two different hyperfine transitions, the so-called type-I and type-II MOTs [41,42]. The type-I MOT is made by tuning the MOT laser to the F = 2 → F ′ = 3 transition.…”
