Abstract
We demonstrate a quasi-electrostatic trap for cold Cs atoms, using a f ocused 20-W CO2 laser beam (lambda = 10.6 mu m). Excluding gas colliso ns, we measure a trap loss rate of 0.30(33) atoms/s, which is consiste nt with the calculated photon-limited loss rate of 3 x 10(-11) atoms/s . We measure a ground-state hyperfine population relaxation lifetime o f at least 10 s. (C) 1996 Optical Society of America
