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
Strong reducing of the laser focal volume

Author: Godin, T ; Ngcobo, Sandile ; Cagniot, E ; Fromager, M ; Forbes, A ; Aït-Ameur, K Date: Aug 2011 Many 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
Transverse correlation vanishing due to phase aberrations

Author: Godin, T ; Forbes, A ; Naidoo, Darryl ; Fromager, M ; Cagniot, E ; Aït-Ameur, K Date: Jun 2011 The concept of transverse correlation vanishing, between the fraction of power contained in the centre and wings of a probe beam, recently introduced [Opt. Commun. 282 (2009) 3854–3858] is important to be considered when measuring the effective ... Read more
Transverse mode selection in a monolithic microchip laser

Author: Naidoo, Darryl ; Godin, T ; Fromager, M ; Cagniot, E ; Passilly, N ; Forbes, A ; Aït-Ameur, K Date: Nov 2011 The article outlines an approach to mode selection in a microchip laser through judicious shaping of the pump light to create a high modal overlap with the desired mode. The authors demonstrate the principle by creating a donut-shaped pump ... Read more
