Abstract
The possibility of using a laser gyroscope with circular polarization of waves and a Zeeman frequency biasing for conducting various types of geophysical measurements is investigated. The first results of measuring the Earth’s rotation velocity by a Zeeman laser gyroscope with a perimeter of 20 cm in the underground laboratory of the BNO INR RAS are presented under conditions of maximum exclusion of external influencing factors − with thermal stabilization, shielding of electromagnetic fields, and minimization of seismic noise. An increase in the registration sensitivity by an order of magnitude (up to 10–3 grad/hour) is noted compared to previously experiments in the urban ground-based laboratory. The possibility of continuous operation of the installation in a remote mode for more than 6 months is shown.
