Laser Interferometry and Gravitational Wave Astronomy
This department's research focus is on the development and operation of gravitational-wave detectors on Earth. This comprises also a full range of supporting laboratory experiments in quantum optics and laser physics.
After decades of development, gravitational-wave research has finally reached its goal: Today's observatories have achieved the sensitivity required for direct detection of gravitational waves. Almost 400 signals observed as of now and completely new insights into our universe are witnesses to this success. Scientists of the “Laser Interferometry and Gravitational Wave Astronomy” department are world leaders in the development of gravitational-wave detectors on Earth as well as in space.
Interferometry on Earth
Together with British colleagues, researchers from the department operate the GEO600 gravitational-wave detector and develop new state-of-the-art technology. Many of the methods developed here – such as the high-power laser systems of the detectors – are used in all major gravitational-wave observatories in the world. In this international collaboration, the scientists are making key contributions to the technology of future detectors. They are also significantly involved in the development of the “Einstein Telescope”, the European third-generation gravitational-wave detector.
