Fabrication, Testing, Coating and Alignment of Fast Segmented Optics

Abstract

The report presents the results of the MRI addressing four of the most critical technologies needed to produce large-aperture, lightweight, high-power HEL systems. They are: polishing large off-axis segments of fast primary mirrors; testing large segments in an off-axis geometry; alignment of multiple segments of a large mirror; and coatings that reflect high-intensity light without distorting the substrate. The program made substantial progress in all areas. Some of the most important results are the manufacture of a 1.7 m off-axis mirror segment; demonstration of new, powerful measurement techniques using computer-generated holograms; and the first-ever thin-film coating with negative thermal expansion.
