Recycling 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 کاملSqueezing and Dual Recycling in Laser Interferometric Gravitational Wave Detectors
We calculate the response of an ideal Michelson interferometer incorporating both dual recycling and squeezed light to gravitational waves. The photon counting noise has contributions from the light which is sent in through the input ports as well as the vacuum modes at sideband frequencies generated by the gravitational waves. The minimum detectable gravity wave amplitude depends on the freque...
متن کاملModel of thermal wave-front distortion in interferometric gravitational- wave detectors. I. Thermal focusing
We develop a steady-state analytical and numerical model of the optical response of power-recycled Fabry– Perot Michelson laser gravitational-wave detectors to nonlinear thermal focusing in optical substrates. We assume that the thermal distortions are small enough that we can represent all intracavity fields as linear combinations of basis functions derived from the eigenmodes of a Fabry–Perot...
متن کاملDynamics 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 کاملOptimization of thermal noise in multi-loop pendulum suspensions for use in interferometric gravitational-wave detectors
We study the thermal-noise spectrum of multi-loop pendulum suspensions for test masses in interferometric gravitational-wave detectors. The dependence of the thermal noise on suspension parameters and on properties of the wire material is discussed for the situation in which the losses are dominated by the internal friction in the pendulum wires.
