Abstract

We present results on a free-space atom interferometer operating on the first order magnetically insensitive |F=1,mF=0〉→|F=2,mF=0〉 ground state transition of Bose-condensed 87Rb 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.

Fig. 1.

(a) Level scheme and (b) experimental setup of the Raman beam splitters for the atom interferometer. The atom laser pulse propagates under gravity through the two beam splitters and is subsequently imaged via a state selective absorption imaging scheme. Splitting the optical beam path with a calcite crystal close to the atom laser interferometer allows for improved relative stability of the two beam splitter positions. The light source is an external cavity diode laser (ECDL), in combination with an electro-optic modulator (EOM) placed in one arm of a Mach-Zehnder interferometer (MZI).

Fig. 2.

Ramsey fringes measured over a range of 6.5kHz. The red solid curve shows an experimental data set, and the blue dashed curve depicts simulated Ramsey fringes for comparable experimental conditions. The upper (lower) clouds of atoms in the absorption pictures above the graph show the population in the |F=2,mF =0〉 (|F=1,mF =0〉) state, for different detunings from two-photon resonance. Two adjacent absorption pictures correspond to a frequency difference of 20Hz.

Noise measurement for a typical sequence of Ramsey fringes. Each data point is averaged over five experimental runs. The red dots (blue circles) show the population in the |F=2,mF =0〉(|F=1,mF =0〉) state.
