Abstract
Laser beams containing higher-order phase singularities can be produce d with high efficiency computer generated holograms made with very sim ple equipment. Using such holograms in an optical tweezers experiment we have successfully trapped reflective and absorptive particles in th e dark central spot of a focused charge 3 singularity beam. Angular mo mentum absorbed from the beam can set particles into rotation.
