Gravitational waves have been predicted by Einstein in his General Relativity theory. They are perturbation of the space-time metric and we try to reveal them by laser interferometry. More precisely, gravitational wave detectors are km long Michelson interferometers combined with Fabry-Perot cavities. The network of first generation detectors (Virgo, LIGO, GEO) did not permit a direct detection after several observational runs in coincidence at the nominal sensitivity. A second generation of detectors is in preparation with in particular the European project Advanced Virgo which should have a sensitivity increased by an order of magnitude compared to Virgo. The interferometer mirrors play a crucial role in the Advanced Virgo sensitivity. Th...
