|Title:||All-optical Bose-Einstein condensation in a 1.06 μm dipole trap||Authors:||Arnold, K.J.
|Issue Date:||15-Jun-2011||Citation:||Arnold, K.J., Barrett, M.D. (2011-06-15). All-optical Bose-Einstein condensation in a 1.06 μm dipole trap. Optics Communications 284 (13) : 3288-3291. ScholarBank@NUS Repository. https://doi.org/10.1016/j.optcom.2011.03.008||Abstract:||We report the all-optical production of a 87Rb Bose-Einstein condensate (BEC) in a simple 1.06 μm dipole trap experiment. We load a single beam dipole trap directly from a magneto-optic trap (MOT). After evaporation in the single beam, a second crossed beam is used for compression. The intensity in both beams is then reduced for evaporation to BEC. We obtain a BEC with 3.5 × 104 atoms after 3 s of total evaporation time. We also give a detailed account of the thermal distribution in cross beam traps. This account highlights the possible difficulties in using shorter wavelength lasers to condense all optically. © 2011 Elsevier B.V.
