Spectrum of phase noise in the Dulkyn pentagonal ring interferometer and test experiments to detect a weak periodic signal

Results of the first long-term experiments using a pentagonal interferometer are described. These experiments were used to refine the detection of a given simulated signal against a noise background. Pis’ma Zh. Tekh. Fiz. 24, 86–92 (November 26, 1998)     

Processing the Signal Response of the Dulkyn Gravitational-Wave Detector

Systems are considered for stabilizing the frequency and phase differences of the optical radiations in the resonators of the Dulkyn gravitational-wave detector laser system. Algorithms are proposed for processing the signal response of the detector to the action of gravitational radiation and these make it possible to observe a detected signal with a signal-to-noise ratio of the order of 50 when the signal-to-noise ratio at the output of the optical part of the system is lower than 10^–7.     

Detection of gravity wave signals with drift of the geometric dimensions of the detector

Test of local position invariance at the detector “Dulkyn-1”

We present the results of testing local position invariance in a “null” gravitational red-shift experiment, carried out in the framework of the Research and Engineering Project “Dulkyn.” The experimental data, collected during the five-month operation of a double-cavity laser system, where one cavity operated in the free generation mode while the frequency of the second cavity was stabilized by the nonlinear supernarrow absorption resonance of the methane molecule, confirmed the universality of the gravitational redshift law at a level of 0.9%.
