GRAVITATION-WAVE DETECTOR Russian patent published in 2009 - IPC G01V7/00 

FIELD: physics, measurement.

SUBSTANCE: invention is related to laser-interferometric gravitation-wave (GW) detectors and may be used for detection of low-frequency periodical gravitation-wave signals from binary relativistic astrophysical objects. Substance of invention consists in the fact that due to introduction of double-resonator laser system of auxiliary and end mirrors into each resonator, as well as semitransparent plate and polariser, easier performance of alignment, adjustment and spatial separation of optical resonator radiations is achieved, which results in more reliable and stable operation of GW detector laser system.

EFFECT: development of GW detector on the basis of double-resonator laser system with common active medium and geometrically non-equivalent contours.
