Abstract
We demonstrate an ultrastable laser trap that provides tight confinement of neutral atoms with negligible optical scattering and minimal laser-noise-induced heating. Using this method, fermionic atoms are stored in a 0.4 mK deep well with a trap lifetime of 300 sec, consistent with a background pressure of . To our knowledge, this is the longest storage time ever achieved with an all-optical trap, comparable to the best reported magnetic traps.
