Author:Naidoo, Darryl; Forbes, A; Aït-Ameur, K; Fromager, MDate:Jan 2011A method of decomposing a dual-directional laser beam into a forward propagating field and a backward propagating field for an apertured plano-concave cavity is presented. An intra-cavity aperture is a simple method of laser beam shaping as ...Read more
Author:Naidoo, Darryl; Godin, T; Fromager, M; Aït-Ameur, K; Forbes, ADate:Feb 2014We explore an interferometric beam shaping technique that considers the coaxial superposition of two Gaussian beams. This technique is traditionally implemented in a Mach-Zehnder interferometer; however, to avoid phase shift drift due to ...Read more
Author:Godin, T; Ngcobo, Sandile; Cagniot, E; Fromager, M; Forbes, A; Aït-Ameur, KDate:Aug 2011Many applications of lasers seek nowadays for focal spots whose corresponding volume is getting smaller and smaller in order to ensure high spatial resolution. This problem, studied by many research groups around the world, is the core of ...Read more
