Abstract

We propose and investigate a technique for generating smooth two-dimensional potentials for ultra-cold atoms based on the rapid scanning of a far-detuned laser beam using a two-dimensional acousto-optical modulator (AOM). We demonstrate the implementation of a feed-forward mechanism for fast and accurate control of the spatial intensity of the laser beam, resulting in improved homogeneity for the atom trap. This technique could be used to generate a smooth toroidal trap that would be useful for static and dynamic experiments on superfluidity and persistent currents with ultra-cold atoms.

Fig. 1.

Trapping frequencies as a function of ring size for a beam waist of 25µm. The minimum in this plot shows the regime where the radius a of the ring is of the same size as the focus of the laser focus and the minimum of the potential in the center of the trap <0.

Fig. 2.
Fig. 2.

Feed-forward technique to cancel the effect of different diffraction efficiencies depending on the angle of deflection. When the intensity locked laser beam is scanned it is imaged on a CCD camera and some part of it is deflected onto a photo diode. The photo diode gives an intensity profile that is then inverted and mixed with the rf signal that drives the AOM. Extra modulations of the intensity over the ring can be accomplished with an additional signal to the intensity lock.

Fig. 3.
Fig. 3.

Intensity profiles of the rings without (top curve) and with (bottom curve) feed-forward. Corresponding CCD images are shown in figure 5, where the first image shows the uncorrected and the second image the corrected ring.

Fig. 4.
Fig. 4.

Condensate fraction of a BEC in a magnetic trap with an optical dipole trap super-imposed run with a 20% on/off duty cycle. Initial condensate fraction without dipole trap was 15.3% and is indicated in gray. The line through the data points acts only as a guide to the eye.

Fig. 5.
Fig. 5.

Different possible waveforms for the function generator controlling the feed-forward technique and the function generator controlling the PID circuit and the resulting patterns. The top pattern shows a uniform distribution for both function generators resulting in a ring with non-uniform light distribution. For all the other cases the first generator is used to cancel the effects of different diffraction efficiencies and the second generator to create patterns of laser power leading to a uniform ring, horse shoe and ring lattice, respectively. The size of the images is 330×330µm.
