Light Pulse Atom Interferometric Decive

An atomic interferometric device useful, e.g., for measuring acceleration or rotation is provided.  The device comprises at least one vapor cell containing a Raman-active chemical species, an optical system, and at least one detector.  The optical system is conformed to implement a Raman pulse interferometer in which Raman transitions are stimulated in a warm vapor of the Raman-active chemical species.  The detector is conformed to detect changes in the populations of different internal states of atoms that have been irradiated by the optical system.
