We demonstrate an all-optical technique to evaporatively produce sodium Bose–Einstein condensates (BEC). We use a crossed-dipole trap formed from light near 1 μm, and a simple ramp of the intensity to force evaporation. In addition, we introduce photoassociation as diagnostic of the trap loading pro...
