Amplification of higher-order Poincaré sphere beams

Author: Naidoo, Darryl ; Sroor, H ; Litvin, I ; Forbes, A Date: Sep 2019 The Higher order Poincar´e sphere (HOPS) is generally used to describe scalar and vector orbital angular momentum modes. These modes have found many applications to date; however, they are limited to low power levels. It has thus become topical ... Read more
Fractal light from lasers

Author: Sroor, H ; Naidoo, Darryl ; Miller, SW ; Nelson, J ; Courtial, J ; Forbes, A Date: Jan 2019 Fractals, complex shapes with structure at multiple scales, have long been observed in Nature: as symmetric fractals in plants and sea shells, and as statistical fractals in clouds, mountains and coastlines. With their highly polished spherical ... Read more
A novel laser resonator for fractal modes

Author: Sroor, H ; Naidoo, Darryl ; Courtial, J ; Forbes, A Date: Feb 2018 Mathematical self-similar fractals manifest identical replicated patterns at every scale. Recently, fractals have found their way into a myriad of applications. In optics, it has been shown that manipulation of unstable resonator parameters ... Read more
Purity of vector vortex beams through a birefringent amplifier

Author: Sroor, H ; Lisa, Nyameko ; Naidoo, Darryl ; Litvin, Ihar ; Forbes, A Date: Apr 2018 Creating high-quality vector vortex (VV) beams is possible with a myriad of techniques at low power, and while a few studies have produced such beams at high power, none have considered the impact of amplification on the vector purity. Here ... Read more
