We report on the experimental demonstration of a horizontal accelerometer based on atom interferometry using counterpropagative Raman transitions between the states $F=1,m_F=\mp1$ and $F=2,m_F=\pm1$ of $^{87}$Rb. Compared to the $F=1,m_F=0 \leftrightarrow F=2,m_F=0$ transition usually used in atom interferometry, our scheme presents the advantages to have only a single counterpropagating transition allowed in a retroreected geometry, to use the same polarization configuration than the magneto-optical trap and to allow the control of the atom trajectory with magnetic forces. We demonstrate horizontal acceleration measurement in a close-to-zero velocity regime using a singlediffraction Raman process with a short-term sensitivity of $25 \times 10^{-5}$ m.s$^{-2}$.Hz$^{-1/2}$. We discuss specific features of the technique such as spontaneous emission, light-shifts and effects of magnetic field inhomogeneities. We finally give possible applications of this technique in metrology or for cold-atom inertial sensors dedicated to onboard applications. |
