Abstract

We report on the implementation of an optical tweezer system for controlled transport of ultracold atoms along a narrow, static confinement channel. The tweezer system is based on high-efficiency acousto-optic deflectors and offers two-dimensional control over beam position. This opens up the possibility for tracking the transport channel when shuttling atomic clouds along it, forestalling atom spilling. Multiple clouds can be tracked independently by time-shared tweezer beams addressing individual sites in the channel. The deflectors are controlled using a multichannel direct digital synthesizer, which receives instructions on a submicrosecond time scale from a field-programmable gate array. Using the tweezer system, we demonstrate sequential binary splitting of an ultracold Rb87 cloud into 25 clouds.

(a) Absorption images showing the production (ii–vi) of 2, 4, 8, 16, and 32 separate atomic samples in a linear array from a single cloud in a double well (i) (see Media 1). The white bifurcating curve overlaying the frames shows fZ versus time. (b) Axial atom number distributions for arrays with 16 (solid black line) and 32 sites (dashed blue line).

Crossed optical dipole traps and trapping geometry. Example showing vertical tweezer I aligned to intersect the axis of the horizontal waveguide, while tweezer II is offset in the x direction. The latter leads to leakage and loss of atoms.

Fig. 5.
Fig. 5.

Crossed-trap lifetimes along the waveguide; Squares show single-channel FSK with fX=72.4MHz (fixed) optimized for z=0; circles show dual-channel FSK with fX varying linearly with z and optimized lifetimes at z=±1.8mm. Optimizations were based on the data displayed in the insets: number of atoms remaining 100 ms after loading the site versus fX at z={1.8,0,1.8}mm. Optimized fX(z) trajectories for single- and dual-channel FSK are shown as solid blue and dashed black lines, respectively.
