“…The orientation of the magnetic field inside the apparatus defines a preferred quantization axis, which in turn determines the polarization of laser beams. In the different Zeeman slower implementations, the magnetic field is either colinear [1][2][3][4][5][6][7][8][9] or orthogonal to the atom propagation axis [9][10][11][12][13]. In the first case, pure circular polarization of the laser beam is achievable, allowing for an atom-light interaction limited to a cycling transition,within an effective two-level system.…”

We present a thorough analysis of a Zeeman slower for sodium atoms made of permanent magnets in a Halbach configuration. Due to the orientation of the magnetic field, the polarisation of the slowing laser beam cannot be purely circular leading to optical leakages into dark states. To circumvent this effect, we propose an atomic state preparation stage able to significantly increase the performances of the Zeeman slower. After a careful theoretical analysis of the problem, we experimentally implement an optical pumping stage leading to an increase of the magneto-optical trap loading rate by 3.5. Such method is easy to set up and could be extended to other Zeeman slower architectures.

We describe a simple Zeeman slower design using permanent magnets. Contrary to common wire-wound setups no electric power and water cooling are required. In addition, the whole system can be assembled and disassembled at will. The magnetic field is however transverse to the atomic motion and an extra repumper laser is necessary. A Halbach configuration of the magnets produces a high quality magnetic field and no further adjustment is needed. After optimization of the laser parameters, the apparatus produces an intense beam of slow and cold 87 Rb atoms. With typical fluxes of 1 to 5 × 10 10 atoms/s at 30 m · s −1 , our apparatus efficiently loads a large magneto-optical trap with more than 10 10 atoms in one second, which is an ideal starting point for degenerate quantum gases experiments.
