Tapered-amplified AR-coated laser diodes for Potassium and Rubidium atomic-physics experiments
Robert A. Nyman, Gael Varoquaux, Brice Villier +5
We present a system of room-temperature extended-cavity grating-diode lasers (ECDL) for production of light in the range 760-790nm. The extension of the tuning range towards the bl…
Inhibition of Transport of a Bose-Einstein Condensate in a Random Potential
Jocelyn Retter, Andres F. Varon, David Clément +6
We observe the suppression of the 1D transport of an interacting elongated Bose-Einstein condensate in a random potential with a standard deviation small compared to the typical en…
An Atom Trap Relying on Optical Pumping
P. Bouyer, P. Lemonde, M. Ben Dahan +3
We have investigated a new radiation pressure trap which relies on optical pumping and does not require any magnetic field. It employs six circularly polarized divergent beams and…
Beam quality of a non-ideal atom laser
J. -F. Riou, W. Guerin, Y. Le Coq +4
We study the propagation of a non-interacting atom laser distorted by the strong lensing effect of the Bose-Einstein Condensate (BEC) from which it is outcoupled. We observe a tran…
Partially ferromagnetic electromagnet for trapping and cooling neutral atoms to quantum degeneracy
Marie Fauquembergue, Jean-Félix Riou, William Guerin +7
We have developed a compact partially ferromagnetic electromagnet to produce a Ioffe-Pritchard trap for neutral atoms. Our structure permits strong magnetic confinement with low po…
Influence of optical aberrations in an atomic gyroscope
Jerome Fils, Florence Leduc, Philippe Bouyer +4
In atom interferometry based on light-induced diffraction, the optical aberrations of the laser beam splitters are a dominant source of noise and systematic effect. In an atomic gy…
