The field propagation is described using the scalar Collins diffraction integral, and the resulting intensity, optical potential, gradient force, and scattering force are analyzed for a polystyrene nanosphere and an air bubble in water. The results demonstrate that the parity of the radial mode index\n                    <jats:italic>p<\/jats:italic>\n                    provides discrete control over the three-dimensional trapping topology.
