Atom lasers: Production, properties and prospects for precision inertial measurement

NP Robins, PA Altin, JE Debs, JD Close - Physics Reports, 2013 - Elsevier
We review experimental progress on atom lasers out-coupled from Bose–Einstein
condensates, and consider the properties of such beams in the context of precision inertial …

Guided quasicontinuous atom laser

W Guerin, JF Riou, JP Gaebler, V Josse, P Bouyer… - Physical Review Letters, 2006 - APS
We report the first realization of a guided quasicontinuous atom laser by rf outcoupling a
Bose-Einstein condensate from a hybrid optomagnetic trap into a horizontal atomic …

Generating quadrature squeezing in an atom laser through self-interaction

MT Johnsson, SA Haine - Physical review letters, 2007 - APS
We describe a scheme for creating quadrature-and intensity-squeezed atom lasers that do
not require squeezed light as an input. The beam becomes squeezed due to nonlinear …

NP Robins, C Figl, M Jeppesen, GR Dennis, JD Close - Nature Physics, 2008 - nature.com
The atom laser, a bright, coherent matter wave derived from a Bose–Einstein condensate,
holds great promise for precision measurement and for fundamental tests of quantum …

Continuous guided strontium beam with high phase-space density

CC Chen, S Bennetts, RG Escudero, B Pasquiou… - Physical Review …, 2019 - APS
A continuous guided atomic beam of Sr 88 with a phase-space density exceeding 10− 4 in
the moving frame and a flux of 3× 10 7 at. s− 1 is demonstrated. This phase-space density is …

Optimal matter-wave gravimetry

M Kritsotakis, SS Szigeti, JA Dunningham, SA Haine - Physical Review A, 2018 - APS
We calculate quantum and classical Fisher information for gravity sensors based on matter-
wave interference, and find that current Mach-Zehnder interferometry is not optimally …

Coherent three-photon excitation of the strontium clock transition

J He, B Pasquiou, RG Escudero, S Zhou… - arxiv preprint arxiv …, 2024 - arxiv.org
We recently demonstrated a continuous Bose-Einstein condensate of strontium atoms. We
could turn this into a continuous-wave atom laser if an efficient outcoupling mechanism is …

The space atom laser: an isotropic source for ultra-cold atoms in microgravity

M Meister, A Roura, EM Rasel… - New Journal of …, 2019 - iopscience.iop.org
Atom laser experiments with Bose–Einstein condensates (BECs) performed in ground-
based laboratories feature a coherent and directed beam of atoms which is accelerated by …

Feedback control of an interacting Bose-Einstein condensate using phase-contrast imaging

SS Szigeti, MR Hush, ARR Carvalho, JJ Hope - Physical Review A—Atomic …, 2010 - APS
The linewidth of an atom laser is limited by density fluctuations in the Bose-Einstein
condensate (BEC) from which the atom laser beam is outcoupled. In this paper we show that …

An ultra-bright atom laser

V Bolpasi, NK Efremidis, MJ Morrissey… - New Journal of …, 2014 - iopscience.iop.org
We present a novel, ultra-bright atom laser and an ultra-cold thermal atom beam. Using rf-
radiation we strongly couple the magnetic hyperfine levels of 87 Rb atoms in a trapped Bose …
