Abstract

Antares is a 24-beam CO₂ laser system for controlled fusion research, under construction at Los Alamos National Laboratory. Rapid automatic alignment of this system is required prior to each experimental shot. Unique opto-mechanical alignment devices, which have been developed specifically for this automatic alignment system, are discussed. A variable focus alignment telescope views point light sources. A beam expander/spatial filter processes both a visible krypton-ion and a 10.6 μm CO₂ alignment laser. A periscope/carousel device provides the means by which the alignment telescope can sequentially view each of 12 optical trains in each power amplifier. The polyhedron alignment device projects a point-light source for both centering and pointing alignment at the polyhedron mirror. A rotating wedge alignment device provides a sequencing point-light source and also compensates for dispersion between visible and 10.6 μm radiation. A back reflector "flip-in" remotely positions point-light sources at the back-reflector mirrors. A light source box illuminates optic fibers with high-intensity white light which is distributed to the various point-light sources in the system.
