Author:Ngcobo, Sandile; Litvin, I; Burger, L; Forbes, ADate:Aug 2013Customizing the output beam shape from a laser invariably involves specialized optical elements in the form of apertures, diffractive optics and free-form mirrors. Such optics require considerable design and fabrication effort and suffer from ...Read more
Author:Du Preez, NC; Forbes, A; Botha, LRDate:Sep 2009In this paper researchers present the design of a CO2 laser resonator that produces as the stable transverse mode a super–Gaussian laser beam. The resonator makes use of an intra–cavity diffractive mirror and a flat output coupler, generating ...Read more
Author:Forbes, A; Du Preez, NC; Belyi, VN; Botha, LRDate:Aug 2009In this paper the researchers present results on improved paint stripping performance with an intra-cavity generated Flattened Gaussian Beam (FGB). A resonator with suitable diffractive optical elements was designed in order to produce a ...Read more
