GRAVITATION-WAVE DETECTOR Russian patent published in 2001 - IPC

FIELD: gravitation-wave astronomy. SUBSTANCE: gravitation-wave detector is related to laser-interferometric gravitation-wave detectors used to detect low-frequency periodic gravitation-wave signals from duel relativistic astrophysical objects. Absorbing cell is brought into reference circuit of double resonator laser system of pentagon configuration with geometrically non- equivalent loops with common active and reflecting elements. As result generation frequency of reference resonator of laser system is determined by inherent frequency of emission of atoms from absorbing cell only which does not change under effect of gravitation-wave signal, that is, phase incursion in optical radiation of reference resonator under effect of gravitation-wave signal is excluded. That is why output legitimate signal of gravitation-wave detector does not depend on orientation of laser system with reference to source of gravitational radiation and necessity of prolongation of time for accumulation of legitimate signal to required signal-to-noise ratio is avoided. EFFECT: enhanced functional efficiency of gravitation-wave detector. 1 dwg
