Generation of shape-invariant flat-top laser beams

Author: Ait-Ameur, K ; Naidoo, Darryl ; Ngcobo, Sandile ; Fromager, M ; Litvin, I ; Hasnaoui, A ; Harfouche, A ; Forbes, A Date: Feb 2015 A great number of laser applications need in place of the usual Gaussian beam a flat-top intensity profile in the focal plane of a focusing lens. In general the transformation of the laser beam from the Gaussian to the flat-top shape is made ... Read more
Selection of a LGp0-shaped fundamental mode in a laser cavity: Phase versus amplitude masks

Author: Hasnaoui, A ; Godin, T ; Cagniot, E ; Fromager, M ; Forbes, A ; Ait-Ameur, K Date: 2012 Laser beams of a single high-order transverse mode have been of interest to the laser community for several years now. In order to achieve such a mode as the fundamental mode of the cavity, mode selecting elements in the form of a phase or ... Read more
