Abstract

We demonstrate the transfer of potassium atoms from a vapor-cell type magneto-optical trap (MOT) to a second MOT up to 75 cm away with the use of a spatially narrow push laser that generates a 40-m/s atomic beam. By adding two-dimensional MOT’s (atomic funnels) along the transfer path to generate transverse cooling and compression of the beam, we can consistently transfer 78±10% of the atoms.

Layout of the double magneto-optical trap system. With a single atomic funnel the separation between trap centers is 48 cm. This is increased to 75 cm with the addition of a second funnel.

Fig. 2
Fig. 2

Laser schematic. The beams for the first and the second magneto-optical traps (MOT’s) and for the push are independently tunable with acousto-optical modulators (AOM’s), which allow both the trapping and transfer efficiencies to be maximized.

Fluorescence signal from the detection trap used in time-of-flight analysis (×). The solid curve is a fit to the data that yields the mean velocity and the velocity spread.

Fig. 6

Population-transfer variation with push-beam detuning. The × symbol (+ symbol) denotes helicity of circular polarization that matches (opposes) the helicity of the ingoing trap light with equal power in the trap and repump frequencies. The push power is 0.8 mW.
