Abstract

We describe an all-optical method of making a ⁸⁷Rb Bose-Einstein condensate (BEC). Atoms are first cooled in an optical lattice and loaded into a crossed dipole trap with 1.06 μm light. Then the density is increased by dynamically reducing the trap size, while the atoms are evaporatively cooled by reducing the light intensity. Every 3.3 s, we obtain a nearly pure BEC with 3.5 × 10 ⁵ atoms in their lowest internal energy state.
