Ultrastable CO2laser trapping of lithium fermions

Journal Article (Journal Article)

We demonstrate an ultrastable CO2laser trap that provides tight confinement of neutral atoms with negligible optical scattering and minimal laser-noise-induced heating. Using this method, fermionic6Li atoms are stored in a 0.4 mK deep well with a 1/e trap lifetime of 300 sec, consistent with a background pressure of 10-11Torr. To our knowledge, this is the longest storage time ever achieved with an all-optical trap, comparable to the best reported magnetic traps. © 1999 The American Physical Society.
