We demonstrate a quasi-electrostatic trap (QUEST) for cold Cs atoms using a focused 20W CO 2 laser beam (λ=10.6µm). Excluding background gas collisions, we measure a trap loss rate of 0.30(33) atoms/s, which is consistent with the calculated photon-limited loss rate of 3x10 -1 1 atoms/s. We measure a ground state hyperfine population relaxation lifetime of at least 10s.doi:10.1364/ol.21.000077 pmid:19865310 fatcat:27wdgtr2jbemzoclyeikngvgpe
