Diffusion of Co and W in diamond tool induced by 10.6 µm CO2 laser radiation

Author: Masina, Bathusile N ; Forbes, Andrew ; Mwakikunga, Bonex W ; Bodkin, R Date: May 2011 At present it is known that diamond tools degrade with time as it is normally used at high temperatures. One of the questions the authors like to answer in this study is whether thermally induced problems in diamond tool arise as a result of ... Read more
Thermally induced lensing determination from the coefficient of defocus aberration

Author: Bell, Teboho ; Naidoo, Darryl ; Forbes, Andrew Date: Jul 2014 The effects of a temperature gradient in a laser crystal in an end-pumped configuration in a solid-state laser resonator results in thermally induced aberrations. Of particular interest we measure the thermally induced lens from the coefficient ... Read more
Vector-mode decay in atmospheric turbulence: An analysis inspired by quantum mechanics

Author: Nape, I ; Mashaba, Nikiwe P ; Mphuthi, N ; Jayakumar, S ; Bhattacharya, S ; Forbes, Andrew Date: Mar 2021 Vector beams are inhomogeneously polarized optical fields with nonseparable, quantum-like correlations between their polarization and spatial components, and hold tremendous promise for classical and quantum communication across various ...
