摘要：

We present results on a free-space atom interferometer operating on the first order magnetically insensitive vertical bar F = 1, m(F) = 0 > -> vertical bar F = 2, m(F) = 0 > ground state transition of Bose-condensed Rb-87 atoms. A pulsed atom laser is output-coupled from a Bose-Einstein condensate and propagates through a sequence of two internal state beam splitters, realized via coherent Raman transitions between the two interfering states. We observe Ramsey fringes with a visibility close to 100% and determine the current and the potentially achievable interferometric phase sensitivity. This system is well suited to testing recent proposals for generating and detecting squeezed atomic states. (C) 2009 Optical Society of America
