Characteristics of a magneto-optical trap of molecules

Abstract: We present the properties of a magneto-optical trap (MOT) of CaF molecules. We study the process of loading the MOT from a decelerated buffer-gascooled beam, and how best to slow this molecular beam in order to capture the most molecules. We determine how the number of molecules, the photon scattering rate, the oscillation frequency, damping constant, temperature, cloud size and lifetime depend on the key parameters of the MOT, especially the intensity and detuning of the main cooling laser. We compare our res… Show more

“…Such control has recently been achieved [10-13] for bialkali molecules produced by associating ultracold atoms [14][15][16][17][18]. Great efforts are also being made to cool molecules directly, for example, by optoelectrical Sisyphus cooling [19] or direct laser cooling and magneto-optical trapping [20][21][22][23][24][25]. These methods can produce ultracold molecules with greater chemical diversity and with large electric and magnetic dipoles, as is often desired.…”

“…Here, we demonstrate coherent control and magnetic trapping of laser-cooled molecules, which are key steps towards the applications discussed above. Starting from a MOT of CaF [25], we compress the cloud to increase its density, cool the molecules to sub-Doppler temperature [23], optically pump them into a single internal state, transfer them coherently to a selectable rotational, hyperfine and Zeeman level, and then confine them in a magnetic trap.Our setup is the same as used previously [23,25], with the addition of microwave components to drive the rotational transition. A pulse of CaF emitted at time t ¼ 0 from a cryogenic buffer gas source [34] is decelerated by frequency-chirped counter-propagating laser light [35].…”
