Dynamics of Laser Interferometric Gravitational Wave Detectors
This thesis is a study of dynamics of the new laser gravitational-wave detectors. The analysis in the thesis is developed primarily for LIGO (Laser Interferometer Gravitational-Wave Observatory) but can be used for other interferometers such as VIRGO and TAMA. The dynamics of fields in the interferometers are described in terms of difference equations which take into account the light transit t...
متن کاملRecycling in laser-interferometric gravitational-wave detectors.
Laser interferometers may detect gravitational waves by sensing the strain in space produced by their passage. The resultant change in intensity of an interference fringe must be observable against a background noise due to the statistical fluctuations in the number of detected photons. Optimization of the detector sensitivity thus involves devising an optical system which both maximizes the si...
متن کاملRadiation pressure and stability of interferometric gravitational-wave detectors.
The effect of radiation pressure on the stability of Fabry-Perot cavities with hanging mirrors is investigated. Such cavities will form an integral part of the laser interferometric gravitational-wave detectors that are being constructed around the globe. The mirrors are hung by means of a pendulum suspension and are locked by servo controls. We assume a realistic servo-control transfer functio...
متن کاملPhysics of Gravitational Wave Detection: Resonant and Interferometric Detectors
I review the physics of ground-based gravitational wave detectors, and summarize the history of their development and use. Special attention is paid to the historical roots of today’s detectors. *Supported by the National Science Foundation, under grant PHY-9602157 @ 1998 Peter R. Saulson.
متن کاملA Photon Calibrator for Interferometric Gravitational Wave Detectors
Photon calibrators use amplitude-modulated lasers to actuate test masses in interferometric gravitational wave detectors. They provide an independent check of the conventional detector calibration obtained via coil actuators. They also have the potential to improve overall calibration precision. Here we describe photon calibrators as currently implemented in LIGO and estimate the precision of t...
