Abstract
We demonsatrate an all optical technique to evaporatively produce sodium Bose-Einsteincondensates (BEC). We use a crossed-dipole trap formed from light near 1 $\mu$m, and a simple ramp of the intensity to force evaporation. In addition, we introduce photoassociation as diagnostic of the trap loading process, and show that it can be used to detect the onset of Bose-Einstein condensation. Finally, we demonstrate that the production of multiple traps with condensates with this technique is straightforward, and that some control over the spinor state of the BEC is achieved by positioning the trap as well.Citation
