One limitation of the operation of large power lasers chains such as Laser MegaJoule, is the issue of laser damage of optical components. Different physical phenomena which depend on both the properties of materials, their conditions of manufacture / preparation and laser irradiation parameters can lead to damage initiation on the surface or in the volume, which will grow under successive irradiation. This effect limits the output power, affects the lifetime of the optical components and the maintenance cost of the laser. It can also cause serious safety problems. To address this issue and increase the lifetime of fused silica components, a laser process called "stabilization" is studied in this thesis, the aim being to treat the damage sit...
