Hollow beam atom tunnel

One of the more promising proposals for guiding and focusing neutral atoms
involves dark hollow laser beams. When the frequency of the laser is detuned to the blue
of resonance, the dipole force the atoms feel in the light confines them to the dark core
where the atoms can be transported with minimal interaction with the light. The ability
of the all-light atom guides to transport large number of ultracold atoms for long
distances without physical walls leads to the possibility of a versatile tool for atom
lithography, atom interferometry, atomic spectroscopy as well as for transporting and
manipulating Bose-Einstein condensates. Furthermore since the atoms transported in alllight
atom guides do not come into contact with matter, they can in principle be used to
transport antimatter as well.
In this work a hollow beam atom tunnel is demonstrated by guiding magnetooptically
trapped ultracold cesium atoms with a hollow core laser beam. The 1mm
diameter diffractionless hollow beam used to construct the atom tunnel was generated
from a TEM00 mode diode laser at 852 nm using a series of axicons and simple lenses.
The axicon generated hollow beam has a dark core extended for most of its diameter and
steep walls suitable for an atom guide. Ultracold cesium atoms loaded into the tunnel
from a MOT spend 90% of their time in the dark, scattering photons only when they
collide with the light walls. We modeled the evolution of atoms using the interaction
between the atoms and the light walls, which agreed well with experimental observations.
The direction and speed of the atoms in the tunnel can be controlled by varying the
detuning of the tunnel beam.
The ability to vary the core size of the hollow beam makes the all-light atom
guide potentially useful for focusing neutral atoms. The atoms could be focused as tight
as the core size of the hollow beam at its waist. This new focusing scheme, called the
atom funnel, would not show spherical and chromatic aberrations that conventional
harmonic focusing suffers from.
