SQUEEZED-LIGHT LASERS FOR GRAVITATIONAL WAVE OBSERVATORIES
The Thirteenth Marcel Grossmann Meeting, 2015A fundamental noise source limiting the measurement sensitivity of interferometric gravitational wave (GW) observatories is the light's quantum noise. While the sensitivity of the first observatory generation was limited by the shot noise at Fourier frequencies above several hundred hertz, the future observatory generations are expected to be limited ...

CEGO: china einstein gravitational wave observatory
2004 Asia-Pacific Radio Science Conference, 2004. Proceedings., 2005Gravitational waves were predicted by Einstein's general relativity. Up to now there has been no direct evidence for gravitational waves. Since the 1990's, laser interferometers have become the dominant detectors for gravitational wave detection, LIGO, Virgo, GEO600 and TAMA300 are the major laser interferometer gravitational wave observatories in the ...

UNDERGROUND GRAVITATIONAL WAVE OBSERVATORIES: KAGRA AND ET
International Journal of Modern Physics D, 2013Future gravitational wave observatories will be realized underground in order to reduce external disturbances, such as seismic, Newtonian and environmental noises. The Japanese gravitational wave telescope KAGRA is under construction at the Kamioka site and the Einstein Telescope gravitational wave observatory is under study in Europe; the common ...

The Laser Interferometer Gravitational-wave Observatory (LIGO)
Optics and Photonics News, 1995The Laser Interferometer Gravitational-wave Observatory (LIGO) project, scheduled for initial operation in 2000, aims to detect and study gravitational waves from astrophysical sources by precision interferometry between suspended test bodies over four-kilometer baselines.

Laser Interferometer Gravitational-wave Observatories: An Overview
Journal of Modern Optics, 1990Abstract The quest to detect gravitational radiation is on the threshold of a new era. Technological developments in the 1980s have led to the point where it is now possible to design an instrument based on the Michelson interferometer which should not only be able to detect gravity waves but should function as an astronomical observatory.

The Laser Interferometer Gravitational-Wave Observatory LIGO
Advances in Space Research, 2000Abstract The Laser Interferometer Gravitational-Wave Observatory (LIGO) Project to develop a terrestrial astronomical observatory for gravitational wave detection is being developed by a Caltech-MIT collaboration. This effort is complementary to plans for detection in space, as it is sensitive to a higher frequency band (10Hz to 10kHz) and therefore ...
