In this thesis, laser-induced damage resistance improvement of fused silica opticsis investigated in the nanosecond regime. This material is used on high power laser facilitiessuch as the Laser Mégajoule. In order to improve the optics life time and to ensure the nominaloperation of this facility, laser induced damage has to be controlled. This phenomenon is anirreversible modification of the components surface because of the interaction between the laserbeam and precursors defects. These defects are a consequence of the synthesis of silica and thepolishing of the optics and their presence can be reduced by a wet etching. This process consistsin an erosion of the surface using a chemical solution however optical properties must remainunchan...
