Аннотация:The design of a large-scale installation is being considered—a large ring laser gyroscope (RLG)—with record sensitivity to variations in the rotation speed and angular inclinations of the laboratory base surface, as well as to the rotational asymmetry of the refractive index of the optical medium, including vacuum. Using such an instrument, located in an underground observatory, it is possible to obtain information relevant to particle physics, quantum field theory, laser physics, astrometry, global geodynamics and seismology. An applied solution could be the early forecast of global cataclysms such as earthquakes. As a practical step to support the project, the results of trial experiments with a small-sized laser gyroscope (LG) are presented.
