Enhancing the area of a Raman atom interferometer using a versatile double-diffraction technique

Abstract

IIn this paper we demonstrate a new scheme for Raman transitions which realize a symmetric momentum-space splitting of 4k4 \hbar k, deflecting the atomic wave-packets into the same internal state. Combining the advantages of Raman and Bragg diffraction, we achieve a three pulse state labelled interferometer, intrinsically insensitive to the main systematics and applicable to all kind of atomic sources. This splitting scheme can be extended to 4Nk4N \hbar k momentum transfer by a multipulse sequence and is implemented on a 8k8 \hbar k interferometer. We demonstrate the area enhancement by measuring inertial forces.
