Orbital angular momentum correlations with a phase-flipped Gaussian mode pump beam

Author: Romero, J ; Giovannini, D ; McLaren, MG ; Galvez, EJ ; Forbes, A ; Padgett, MJ Date: Aug 2012 We report orbital angular momentum (OAM) and angle correlations between signal and idler photons observed when the nonlinear crystal used in spontaneous parametric down-conversion is illuminated by a non-fundamental Gaussian pump beam. We ... Read more
Propagation of obstructed Bessel and Bessel–Gauss beams

Author: Litvin, IA ; McLaren, MG ; Forbes, A Date: Aug 2008 The investigation into Bessel beams has been a topic of immense research during the past 20 years, due to the interesting properties they display. Bessel beams not only exhibit diffraction free propagation, but also reconstruction of the ... Read more
