摘要：

We demonstrate an ultrastable CO2 laser trap that provides tight confinement of neutral atoms with negligible optical scattering and minimal laser-noise-induced heating. Using this method, fermionic Li-6 atoms are stored in a 0.4 mK deep well with a Ile trap lifetime of 300 sec, consistent with a background pressure of 10(-11) Torr. To our knowledge, this is the longest storage time ever achieved with an all-optical trap, comparable to the best reported magnetic traps. [S0031-9007(99)09193-0].
