Abstract

We prepared about half-million thulium atoms at state with the lowest magnetic sublevel in optical dipole trap. A high purity of polarization of atomic cloud is well confirmed by the Stern- Gerlach-type experiment.

Abstract Minimization of internal degrees of freedom is an important step in the cooling of atomic species to degeneracy temperature. Here, we report on the loading of 6 × 10 5 thulium atoms optically polarized at maximum possible magnetic quantum number m F = − 4 state into dipole trap operating at 532 nm. The purity of polarizations of the atoms was experimentally verified using a Stern–Gerlach-type experiment. Experimental measured polarization of the state is m F = − 3.91 ± 0.26 .

Abstract The Zeeman hyperfine state dependent force in a Stern–Gerlach experiment has been exploited to separate and quantitatively detect atoms in different Zeeman hyperfine states in a cold atom cloud of 87 Rb atoms. Using this atomic state detection technique, the quantum state of the atom cloud has been prepared with high efficiency for magnetic trapping application.

Atomic spin polarization by Raman cooling

H. J. Lee, Steven Chu

We have simultaneously spin polarized and subrecoil cooled sodium atoms trapped in a blue detuned optical dipole trap. Temperatures of 1.5 \ensuremath{\mu}K and less have been achieved for atoms which have been polarized into any of three $F=1$ ground-state magnetic sublevels of sodium. The final phase-space density is comparable to the best achieved by an all-optical cooling technique.We have simultaneously spin polarized and subrecoil cooled sodium atoms trapped in a blue detuned optical dipole trap.
