Point absorbers in Advanced LIGO [PDF]

open access: yesApplied Optics, 2021
Small, highly absorbing points are randomly present on the surfaces of the main interferometer optics in Advanced LIGO. The resulting nanometer scale thermo-elastic deformations and substrate lenses from these micron-scale absorbers significantly reduce the sensitivity of the interferometer directly though a reduction in the power ...

Squeezing in Gravitational Wave Detectors

open access: yesGalaxies, 2022
Injecting optical squeezed states of light, a technique known as squeezing, is now a tool for gravitational wave detection. Its ability to reduce quantum noise is helping to reveal more gravitational wave transients, expanding the catalog of observations

Dependence of the detected signal on the kinematic parameters of the satellite in the S-LIGO-E2R space system

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники, 2021
The changes of distances less than ~10–21 are registered during the gravitational wave experiment. This feature determines the minimum size of experimental installations and the frequency range of gravitational wave detectors.
