Controlled generation of higher-order Poincaré sphere beams from a laser

Author: Naidoo, Darryl ; Roux, Filippus S ; Dudley, Angela L ; Litvin, Igor ; Piccirillo, B ; Marrucci, L ; Forbes, A Date: Mar 2016 The angular momentum of light can be described by positions on a higher-order Poincaré sphere, where superpositions of spin and orbital angular momentum states give rise to laser beams that have many applications, from microscopy to materials ...

Development of high-power and high-energy 2 µm bulk solid-state lasers and amplifiers

Author: Koen, W ; Jacobs, Cobus ; Wu, Lorinda ; Strauss, Hencharl J Date: Apr 2016 A selection of 2 µm lasers and amplifiers developed at the CSIR National Laser Centre in South Africa is presented. A diverse range of near diffraction-limited 2 µm lasers and amplifiers were developed which varied from high-energy, ... Read more
Excitation of high-radial-order Laguerre-Gaussian modes in a solid-state laser using lower-loss digitally controlled amplitude mask

Author: Bell, Lebohang T ; Hasnaoui, A ; Ait-Ameur, K ; Ngcobo, Sandile Date: Sep 2017 In this paper, we experimentally demonstrate selective excitation of highradial-order Laguerre-Gaussian (LGp or LGp;0) modes with radial-order, p = 1 - 4 and azimuthal-order, l = 0, using a diode-pump solid-state laser (DPSSL) that is digitally ...

Laser development: Taking physics to industry

Author: Esser, D Date: Oct 2012 In this presentation the development path of new solid-state laser technology, which is taken from the underlying laser physics to challenging real world applications, is shown. Read more
Simple technique to evaluate the thermal lens strength of a laser material. SAIP 2005 Talk C-20

Author: Esser, D ; Preussler, D Date: 2005 The presentation is about the simple technique to measure the thermal lens; Same pumping conditions as real laser; Same cooling configuration as real laser; Comparative experiment made; Nd:YVO4 has smaller thermal lens than Nd:GdVO4; Nd:GdVO4 ...
