Abstract

The hunt for gravitational waves with interferometric gravitational wave detectors is one of the most important research areas in today's experimental physics. After the first direct observation of gravitational waves in Fall of last year, the door to a new field of gravitational wave astronomy has been opened. The talk provides an overview about Advanced LIGO that covers the techniques that were implemented, the limiting noise sources and the use of advanced techniques to extract the signal from the noise and also showcase the detection itself. However, an advanced next generation of gravitational wave detectors will be required in order to systematically probe the universe and to make the step from the detection of gravitational waves to routinely observing them. This will open a new window to the physics of the universe. The presentation will show several techniques that are envisioned to increase the sensitivity further in future detectors.
