Abstract: An optical trap for laser cooling and trapping atoms without needing a magnetic field. Three pairs of parallel counterpropagating laser beams are directed to cross in a vacuum chamber to form a trapping volume. Rather than having a mutually orthogonal arrangement in which the optical axes of each beam pair forms an angle ? of 45° to a reference axis, z, these angles are instead between 5° = ? = 40° to form a tripod-like arrangement. The beam pairs each have a significant overlap between their counter-propagating beams within the trapping volume which can be defined by the sum of the beam half-widths of the beams of each pair not exceeding twice the beam pair separation distance. Moreover, for good trap formation, at least one of the parallel beam pairs should be sufficiently separated, having a beam half-width sum of at least a quarter of the separation distance.
