Abstract
We describe an experiment in which atoms are loaded into a crossed beam far-off-resonant trap (FORT) that is only deep. A high-density sample is prepared in a magneto-optic trap, cooled in a three-dimensional far-off-resonant lattice (FORL), optically pumped into the lowest-energy state, adiabatically released from the FORL, magnetically levitated, and transferred to the final trap with a phase-space density of Spontaneous emission in the FORT is negligible, and we have compressed the atoms in the FORT to a spatial density of Evaporative cooling under these conditions proceeds rapidly.
