  • Du Preez, NC; Forbes, A; Botha, LR (Society of Photo-Optical Instrumentation Engineers (SPIE), 2009-09)
    In 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 ...
  • Forbes, A; Du Preez, NC; Belyi, VN; Botha, LR (Society of Photo-Optical Instrumentation Engineers, 2009-08)
    In 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 ...
