Abstract

As part of the LMJ (Laser Megajoule) program, CEA is building the LIL laser with full size optics and LMJ requirements. SAGEM has been selected as the supplier of large optical components and coatings with very high laser- induced damage threshold. Including spare parts, about 100 mirrors 610*430 mm² with LIDT-3ns>25 J/cm² have to be produced. Using a 5 m³ vacuum chamber and the 100 J/cm² mirror coating process developed at CEA-LETI, with Hafnium and SiO₂ materials, we are now typically in a serial production phase. To date, about thirty mirrors have been delivered. This paper focuses on the acceptance tests performed after coating, at SAGEM then CEA: LIDT measurement and Raster-Scan on samples; reflectance mapping on CEA automatic photometer; reflected wavefront deformation with &nullset; 800 mm/1ω CEA interferometer.
