Abstract
Recent advances in cold atom physics have seen the emergence of the area of atom guiding along hollow core optical fibres and also along light beams.1 Both employ the optical dipole force which for suitably tuned light can restrict the atoms to the dark hollow region of the fibre or the light beam. In this work, we discuss and analyse a novel scheme of channelling cold atoms into a high-order Bessel beam (via a high-order Laguerre-Gaussian beam) and demonstrate an efficient method of producing such beams.
