Author:Belyi, VN; Forbes, A; Kazak, NS; Khilo, NA; Ropot, PIDate:Aug 2009A new type of Bessel-like optical beams, which is distinguished by the dependence on the cone angle from the longitudinal coordinate, is investigated. Such beams have the properties of Bessel beams (ring-spatial spatial spectrum) as well as ...Read more
Author:Roux, FSDate:Jun 2012This report present the presentation on deconstructing quantum decoherence in atmospheric turbulence. The focus was on the classical and quantum scintillation, time vs propagation distance, current paradigm: Paterson model, infinitesimal ...Read more
Author:Litvin, IA; Forbes, ADate:Oct 2009The authors outline a resonator design that allows for the selection of a Gaussian mode by diffractive optical elements. This is made possible by the metamorphosis of a Gaussian beam into a flat-top beam during propagation from one end of the ...Read more
Author:Dudley, Angela L; Majola, N; Chetty, N; Forbes, ADate:Feb 2016The coherent superposition of a Gaussian beam with an optical vortex can be mathematically described to occupy the complex plane. The authors provide a simple analogy between the mathematics, in the form of the complex plane, and the visual ...Read more
Author:Ismail, Y; Mclaren, MG; Forbes, ADate:Jul 2009This presentation provides information on optical trapping and tweezing using a spatial light modulator.Read more
Author:Schulze, C; Dudley, Angela L; Flamm, D; Duparré, M; Forbes, ADate:Jul 2013We present the reconstruction of a laser beam wavefront from its mode spectrum and investigate in detail the impact of distinct aberrations on the mode composition. The measurement principle is presented on a Gaussian beam that is intentionally ...Read more
Author:Roux, FSDate:2009The report present the presentation on vortices in Gaussian beams. The presentation was on the polynomial Gaussian beam, Calculation techniques and general properties of polynomial Gaussian beam, Single vortex beams and Gaussian beams with ...Read more
