Author:Forbes, A; Schulze, C; Flamm, D; Dudley, Angela L; Duparre, MDate:Apr 2013We show how laser beam characterization may be done in real-time with digital holograms. We illustrate the power of the techniques by applying them to a variety of laser sources, from fibers to solid-state.Read more
Author:Schulze, C; Flamm, D; Dudley, Angela L; Forbes, A; Duparr'e, MDate:Feb 2013We present a novel technique to measure the orbital angular momentum (OAM) density of light. The technique is based on modal decomposition, enabling the complete reconstruction of optical fields, including the reconstruction of the beams ...Read more
Author:Schulze, C; Dudley, Angela L; Flamm, D; Duparr, M; Forbes, ADate:Oct 2013We present a novel tool for sorting the orbital angular momentum and to determine the orbital angular momentum density of laser beams, which is based on the use of correlation filters.Read more
Author:Forbes, A; Schulze, C; Ngcobo, Sandile; Flamm, D; Naidoo, Darryl; Dudley, Angela L; Duparre, MDate:Feb 2013Modal decomposition of optical fields as a concept has been in existence for many decades, yet despite its clear applications to laser beam analysis it has nevertheless remained a seldom used tool. With the commercialization of liquid crystal ...Read more
