We demonstrate a horizontal multi-photon atom interferometer driven via Bragg diffraction enhanced in an optical resonator. A large interrogation mode (4 mm 1 /e 2 diameter) is necessary, as the atoms cross the interrogation region with a ballistic trajectory. This large mode is achieved using an 80 cm long degenerate cavity to mediate the light-matter interaction. Using a sub-Doppler cooled 87 Rb source, we observe momentum transfer up to 8 (cid:126) k and demonstrate inertial sensitivity using…

A marginally stable optical resonator for enhanced atom interferometry

We propose a marginally stable optical resonator suitable for atom interferometry. The resonator geometry is based on two flat mirrors at the focal planes of a lens that produces the large beam waist

Doppler compensation for cavity-based atom interferometry.

We propose and demonstrate a scheme for Doppler compensated optical cavity enhancement of atom interferometers at significantly increased mode diameters. This overcomes the primary limitations in

Circulating pulse cavity enhancement as a method for extreme momentum transfer atom interferometry

Large-scale atom interferometers promise unrivaled strain sensitivity to mid-band gravitational waves, and will probe a new parameter space in the search for ultra-light scalar dark matter. These

Atom interferometers with scalable enclosed area.

Bloch oscillations and Bragg diffraction are integrated into light-pulse atom interferometers with large momentum splitting between the interferometer arms, and hence enhanced sensitivity, and the prospects for reaching 100 s of variant Planck's over 2pik are discussed.

Degenerate optical resonator for the enhancement of large laser beams.

This work experimentally studies a degenerate optical cavity, 44-cm long and consisting of two flat mirrors placed in the focal planes of a lens, in a regime of intermediate finesse, and numerically investigates the optical gain reduction for large beam waists using the angular spectrum method.

Atom interferometry with up to 24-photon-momentum-transfer beam splitters.

Up to 24-photon Bragg diffraction as a beam splitter in light-pulse atom interferometers achieves a high visibility of the interference fringes and long pulse separation times that are possible only in atomic fountain setups.

Efficient Adiabatic Spin-Dependent Kicks in an Atom Interferometer.

An atom interferometry technique in which the beam splitter is split into two separate operations, and a single-source gradiometer is realized, in which two interferometers measuring a relative phase originate from the same atomic wave function.

Fast Control of Atom-Light Interaction in a Narrow Linewidth Cavity.

We propose a method to exploit high-finesse optical resonators for light-assisted coherent manipulation of atomic ensembles, overcoming the limit imposed by the finite response time of the cavity.

Fundamental Limitations of Cavity-Assisted Atom Interferometry

Atom interferometry inside an optical cavity was demonstrated in Hamilton et al. (Phys Rev Lett 114:100405, 2015 [1]), where they show a \(\pi /2-\pi -\pi /2\) interferometer with caesium atoms
