Experimental generation of steering odd dark beams of finite length

A. Dreischuh, D. Neshev, G. G. Paulus, H. Walther


We report what we believe to be the first realization of odd dark beams of finite length under controllable initial conditions. We obtain mixed edge-screw phase dislocations by reproducing binary computer-generated holograms. Two effective ways to control the steering of the beams are analyzed experimentally and compared with numerical simulations.
