Triple Michelson Interferometer for a Third-Generation Gravitational Wave Detector

The upcoming European design study ‘Einstein gravitational wave Telescope’ represents the first step towards a substantial, international effort for the design of a third-generation interferometric gravitational wave detector. It is generally believed that third generation instruments cannot be installed into existing infrastructures but will require a new search for optimal detector sites. Con...

Lock acquisition of a gravitational-wave interferometer.

Interferometric gravitational-wave detectors, such as the Laser Interferometer Gravitational Wave Observatory (LIGO) detectors currently under construction, are based on kilometer-scale Michelson interferometers, with sensitivity that is enhanced by addition of multiple coupled optical resonators. Reducing the relative optic motions to bring the system to the resonant operating point is a signi...

Laser Interferometer Gravitational Wave Observatory

We report on a search for gravitational wave bursts using data from the first science run of the LIGO detectors. We focus on bursts with durations ranging from 4 msec to 100 msec, and with significant power in the LIGO sensitivity band of 150 to 3000 Hz. We bound the rate for such detected bursts at less than 1.6 events per day at 90% confidence level. This result is interpreted in terms of the...
