Experimental comparison of Raman and RF outcouplers for high flux atom lasers
J. E. Debs, D. Döring, P. A. Altin +6
We study the properties of an atom laser beam derived from a Bose-Einstein condensate using three different outcouplers, one based on multi-state radio frequency transitions and tw…
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…
Semiclassical limits to the linewidth of an atom laser
Mattias Johnsson, Simon Haine, Joseph Hope +5
We investigate the linewidth of a quasi-continuous atom laser within a semiclassical framework. In the high flux regime, the lasing mode can exhibit a number of undesirable feature…
Frequency shifts of photoassociative spectra of ultracold metastable Helium atoms : a new measurement of the s-wave scattering length
J. Kim, S. Moal, M. Portier +3
We observe light-induced frequency shifts in one-color photoassociative spectra of magnetically trapped He atoms in the metastable state. A pair of ultracold spin-…
