Paired atom laser beams created via four-wave mixing
R. G. Dall, L. J. Byron, A. G. Truscott +3
A method to create paired atom laser beams from a metastable helium atom laser via four-wave mixing is demonstrated. Radio frequency outcoupling is used to extract atoms from a Bos…
A multibeam atom laser: coherent atom beam splitting from a single far detuned laser
J. Dugué, G. Dennis, M. Jeppesen +4
We report the experimental realisation of a multibeam atom laser. A single continuous atom laser is outcoupled from a Bose-Einstein condensate (BEC) via an optical Raman transition…
Approaching the Heisenberg limit in an atom laser
M. Jeppesen, J. Dugué, G. R. Dennis +4
We present experimental and theoretical results showing the improved beam quality and reduced divergence of an atom laser produced by an optical Raman transition, compared to one p…
Generating squeezing in an atom laser through self-interaction
Mattias T. Johnsson, Simon A. Haine
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 interact…
Investigation and comparison of multi-state and two-state atom laser output-couplers
J. Dugue, N. P. Robins, C. Figl +4
We investigate the spatial structure and temporal dynamics created in a Bose-Einstein condensate (BEC) by radio-frequency (RF) atom laser output-couplers using a one-dimensional me…
