Optical dipole traps and atomic waveguides based on Bessel light beams
arXiv:cond-mat/0101215 · doi:10.1103/PhysRevA.63.063602
Abstract
We theoretically investigate the use of Bessel light beams generated using axicons for creating optical dipole traps for cold atoms and atomic waveguiding. Zeroth-order Bessel beams can be used to produce highly elongated dipole traps allowing for the study of one-dimensional trapped gases and realization of a Tonks gas of impentrable bosons. First-order Bessel beams are shown to be able to produce tight confined atomic waveguides over centimeter distances.
