High power infrared super-Gaussian beams: generation, propagation and application

Author: Du Preez, NC ; Forbes, A ; Botha, LR Date: Sep 2009 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 coupler, generating ... Read more
Intracavity mode competition between classes of flat–top beams

Author: Litvin, IA ; Loveday, Philip W ; Long, Craig S ; Kazak, NS ; Belyi, V ; Forbes, A Date: Aug 2008 There are many applications in which a laser beam with a flat–top intensity profile would be ideal, as compared to a laser beam with a non–uniform energy distribution. Standard stable optical resonators will unfortunately not generate such a ... Read more
Paint stripping with high power flattened Gaussian beams

Author: Forbes, A ; Du Preez, NC ; Belyi, VN ; Botha, LR Date: Aug 2009 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 order to produce a ... Read more
