FIELD: physics. ^ SUBSTANCE: invention relates to laser interferometer gravitational wave (GW) detectors and can be used to detect low-frequency periodic GW signals from double relativistic astrophysical objects. According to the invention, the reference resonator of the GW detector includes a cell with nonlinearly absorbing gas, wherein the oscillating frequency of the reference resonator is associated with the frequency of nonlinear absorption resonance of the gas molecules, which enables to make the reference resonator insensitive to the effect of gravitational radiation, which enables the GW detector to detect a GW signal from any direction. The GW detector based on a laser with a signal and a reference resonator enables to keep the reference resonator insensitive to the effect of gravitational radiation for any direction of propagation of the detected GW signal. ^ EFFECT: providing the maximum possible response amplitude of the GW detector for the given direction. ^ 1 dwg |
