Development of viscoelastic thin films to mitigate shock wave-induced laser damage in high power laser systems

Amira Guediche, Laurent Belliard, Bernard Perrin, Marc Duquennoy, Amandine Moiny, Mathieu Lafarie, Michel Boustié, Emilien Lescoute, Philippe Belleville, Hervé Piombini

Spallation effects caused by shock waves in optical components such as those used in the Laser MegaJoule facility during laser operation can lead to material fracture. One solution could be to use a viscoelastic thin film on these fused silica components to reduce the reflection of shock waves from...
