The recent interest in atom-optics has mainly been directed at the manipulation of atomic beams by static fields or lasers. Using an alternative approach we have succeeded in focusing in two dimensions a neutral atomic helium beam at room temperature with a reflective optical element (an atom mirror). Such focusing relies on specular elastic scattering, which leaves the coherence of incoming wavepackets unchanged. 
Focusing a helium atom beam using a quantum-reflection mirror
We demonstrate one-dimensional (1D) focusing of a thermal helium atom beam by quantum reflection from a cylindrical concave quartz mirror at near-grazing incidence. The smallest width of the focusExpand
One-dimensional focusing of an atomic beam by a flat reflector
One-dimensional focusing of an atomic beam from a flat reflector is experimentally demonstrated. Focusing occurs because gravity changes the momentum transfer perpendicular to the surface dependingExpand
Atom lens without chromatic aberrations
We propose a lens for atoms with reduced chromatic aberrations and calculate its focal length and spot size. In our scheme a two-level atom interacts with a near-resonant standing light wave formedExpand
