Abstract

The behavior of atoms in an optical far-off resonance trap is found to depend strongly on the trap polarization. Largc loss rates occur unless the polarization is perfectly linear or perfectly circular, in which case exponential lifetimcs up to 10 s arc observed. Through optimization of trap loading, samples of 4 X 106atoms are obtained in a circularly polarized trap. Spin polarization of 98(1)% is measured. This trap should prove useful for precision mcasurenients such as β-decay asymmetry and should niakc rf cooling possible in optical traps.
