Query: Focusing of atoms with strongly confined light potentials   Focusing of atoms with light potentials is studied. In particular, we
consider strongly confined, cylindrical symmetric potential, and demonstrate
their applications in both red and blue-detuned focusing of atoms. We also
study the influence of aberrations, and find that a resolution of 1 nm should
in principle be possible.
