The Laser MegaJoule (LMJ) is a high-power laser dedicated to laser-plasma experiments. At the beginning of the project in the mid-1990s, an optical metrology laboratory was created at CEA to help accomplish all the steps in the construction of this l

Scratches at the surface of fused silica optics can be detrimental for the performance of optical systems. A carbon dioxide (CO2) laser is an interesting tool to remove those scratches because it can melt efficiently the silica in a rapid and localiz

Optical metrology devices for high-power laser large optics

Autor: Jean-Christophe Poncetta, Gael Gaborit, Stéphane Bouillet, Jérôme Daurios

Publikováno v: SPIE Proceedings.

High power laser systems such as the LMJ laser or the LIL laser, its prototype, require large optical components with very strict and various specifications. Technologies used for the fabrication of these components are now usually compatible of such
