An intense, laser-cooled source of metastable helium atoms

Abstract

One of the advantages of atom optics compared with conventional optics is the ability to increase the brightness of an atomic beam relative to the original source. This arises from the use of dissipative light forces to cool the atoms, thereby increasing the atomic phase space density. We describe progress in the development of a system that increases the brightness of a conventional expanding nozzle source to create an intense, collimated beam of metastable helium atoms.
