More than an order of magnitude reduction in the thermalization time, to less than a second, is observed with the focused off-resonant beam occupying only 0.01% of the volume of the magnetic trap. A new method for testing for thermalization of relatively hot clouds is devised. The cold atoms are loaded from a magneto-optical trap (MOT) of <sup>39</sup>K that has gone through a compressed MOT and sub-Doppler cooling stage. The atoms are prepared in the magnetically stretched |<em>F</em> = 2, <em>m<sub>F</sub></em> = 2〉 state prior to loading into the hybrid trap. We also report a direct loading of <sup>39</sup>K atoms, prepared in the state |<em>F</em> = 1〉, into a single beam dipole trap.</p> 2013-07-30 00:00:00 magnitude reduction thermalization time mot trap beam 39 K atoms 39 K Atomic Physics Molecular Physics
