Cryogenic Sapphire Optical Cavities — •Moritz Nagel, Klaus Döringshoff, Sylvia Schikora, Evgeny V. Kovalchuk, and Achim Peters — Humboldt-Universität zu Berlin, Institut für Physik, AG Optische Metrologie, Newtonstr. 15, 12489 Berlin

We present the status of our work on an ultra-stable cryogenically cooled sapphire optical cavity system, with a prospective thermal noise limited frequency stability better than 3·10−17. These cavities will be used in a high-precision experiment, which will test Lorentz invariance within the 10−20 regime.
