| Zusammenfassung | We present a concept of a mirror for application in high-reflectivity low-noise instruments such as interferometers. The concept is based on an etalon with a metasurface (meta-etalon) on the front and a conventional multilayer stack on the rear surface. The etalon in combination with the metasurface enables a dedicated spatial weighing of the relevant thermal noise processes and by this a substantial reduction of the overall readout thermal noise. As examples, we illustrate the benefit of the proposed etalon for thermal noise in two applications: the test masses of the Einstein Telescope gravitational wave detector and a single-crystalline cavity for laser frequency stabilization. In the Einstein Telescope, the thermal noise of the etalon even at room temperature outperforms existing concepts for operation temperatures at 10 K. For the laser stabilization cavity, a reduction of the modified Allan deviation of an order of magnitude is predicted. |
