Abstract
A computer-generated hologram is used to form an optical beam with a locali zed intensity null at its focus. The beam is a superposition of two Laguerr e-Gaussian modes that are phased so that they interfere destructively to gi ve a beam focus that is surrounded in all directions by regions of higher i ntensity. Beams of this kind will have applications in the optical trapping of macroscopic objects or atoms; hence the term optical bottle beam.
