摘要：

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