The Centre d'Etudes de Limeil-Valenton is currently involved in a project which consists of the construction of a 2 KJ/500TW pulsed Nd:glass laser and which will be devoted to inertial confinement fusion research in France. With 240 laser beams and almost 10 000 m2 in coated area required, the proposed megajoule-class laser will be the largest laser system ever built in the world. The proposed laser conceptual design necessitates 44-cm by 44-cm by 6-cm cavity-end mirrors representing more than 50-m2 of coated area. These dielectric mirrors are made of quarterwave stacks of SiO2 and ZrO2-PVP and are prepared from colloidal suspensions. After a sustained search effort, we have prepared mirrored coatings with up to 99 percent damage thresholds ranging 8-10 J/cm2 at 1053- nm wavelength and with 3-ns pulse duration were achieved. Mirrors with good coating uniformity and weak edge-effect could be produced by dip-coating and laminar-flow coating at room temperature and atmospheric pressure. To satisfy the coating demand, coating equipments and a 1000-m2 sol-gel coating production plant are planned to be built at REOSC- Group SFIM company in order to start producing within schedule and cost goal.
