Laser megajoule optics: II. Wavefront analysis in the testing of large components

Abstract

Laser Megajoule is a very large laser system: 240 beams, each comprised of dozens of optical components 400 millimeters squares, covering the area of a football pitch or two. Specifying the optics in Laser Megajoule is a complex matter, because of the large range of types of defects, classified by their lateral size or scale.
