GEO600 has reached a sensitivity of 2·10^-22/√Hz

The direct detection of gravitational waves is one of the most challenging goals of today's experimental physics. Although gravitational waves emitted in catastrophical astrophysical events like the merging of two dense stars in a binary system or a super nova ... [mehr]

Squeezing the quantum noise of laser light

Light is quantized, and the statistics of the photons results in unpredictable uncertainties of the amplitude and the phase of the light field. This inherent uncertainty results in quantum (shot) noise and limits the phase sensitivity of laser interferometers. ... [mehr]

Interferometry with nano-structured optics

We research and develop nano-structured diffraction gratings to split and recombine laser beams in advanced gravitational wave detectors. These all-reflective components can replace the partly transmissive mirrors used in today's detectors. The sensitivity limiting ... [mehr]

Characterisation and stabilisation of a high-power solid-state laser system for Advanced LIGO

The first direct detection of gravitational waves will mark the beginning of gravitational wave astronomy, opening a new window to the universe. The necessary high detection sensitivity calls for ultra-stable high-power lasers with outstanding beam quality. The AEI ... [mehr]
