Interferometry on Earth
Currently, all existing gravitational-wave detectors are ground-based Michelson-type laser interferometers. The AEI is part of an international collaboration which runs the existing detectors: GEO600, the Virgo detector, and the LIGO detectors. The AEI laboratories house various experiments in this area. The institute also develops design concepts for future ground-based dectectors like the Einstein Telescope and tests new technologies using a small-scale prototype.
