“…The experiment uses an 8 mm spot size, and the optimum parameters do not change significantly if the retroreflection loss of 20 % is included. Finally, the simulation reproduces the smoothly decreasing slope of the capture rate versus the MOT beam power of ref [7].…”

Abstract. We have constructed and modeled a simple and efficient source of slow atoms. From a background vapour loaded magneto-optical trap, a thin laser beam extracts a continuous jet of cold rubidium atoms. In this setup, the extraction column that is typical to leaking MOT systems is created without any optical parts placed inside the vacuum chamber. For detailed analysis, we present a simple 3D numerical simulation of the atomic motion in the presence of multiple saturating laser fields combined with an inhomogeneous magnetic field. At a pressure of P Rb87 = 1 × 10 −8 mbar, the moderate laser power of 10 mW per beam generates a jet of flux Φ = 1.3 × 10 8 atoms/s with a mean velocity of 14 m/s and a divergence of < 20 mrad.

“…Theoretical estimates for near-resonant atom traps concentrate either on the capture [7] or on the cooling [8]. We develop a simple and heuristic generalization of the semiclassical radiation pressure expression for the case of multiple saturating laser fields and inhomogeneous magnetic field.…”

“…Normally the laser beams of a MOT are 1 or 2 cm in diameter, whereas these pyramids are less than a millimeter across. Based on the wellestablished model first described by Lindquist et al [16], the number of atoms N captured in a MOT is expected to scale as N ∝ L 2 u 4 c . Here, the L 2 factor derives from the area of the laser beam, which, in our case, is set by the area of the pyramid opening.…”

Abstract-Ultracold atoms can be manipulated using microfabricated devices known as atom chips. These have significant potential for applications in sensing, metrology, and quantum information processing. To date, the chips are loaded by transfer of atoms from an external macroscopic magnetooptical trap (MOT) into microscopic traps on the chip. This transfer involves a series of steps, which complicate the experimental procedure and lead to atom losses. In this paper, we present a design for integrating a MOT into a silicon wafer by combining a concave pyramidal mirror with a square wire loop. We describe how an array of such traps has been fabricated, and we present magnetic, thermal, and optical properties of the chip.[ 2008-0124]Index Terms-Atom chips, cavity patterning, electrophoretic resist, magnetooptical traps (MOTs).

Atom plus atom equals…︁ vacuum! The destructive interference of atoms is just one of the surprising effects of coherent atoms. The long and winding road from trapping atoms to the atomic laser, passing the peak of the Bose – Einstein condensate, won Ketterle a share in the 2001 Nobel Prize for Physics. The graphic shows pulses of coherent sodium atoms (each containing 105 – 106 atoms produced every 5 ms) falling under gravity and expanding due to mutual interatomic repulsion.
