The realisation of an atomic waveguide will be an important component for t
he development of future atom optic devices such as large angle atom interf
erometers. Hollow optical fibres that employ repulsive (blue detuned) evane
scent light fields to guide the atoms are one approach to this technology.
We report here on multimode guiding of metastable helium (2(3) S-1) atoms t
hrough hollow optical fibres that support multimode light fields. In order
to produce efficient single-mode atom guiding, hollow fibres supporting sin
gle light mode propagation will be required to generate uniform evanescent
light fields inside fibre wall. We have recently developed such a fibre and
report on the suitability of its light transmission characteristics for at
om waveguiding. (C) 2001 Academie des sciences/Editions scientifiques et me
