Creation of Conditions for the Maximum Suppression of Magnetic Field Influence on Zero Drift in Four-Frequency and Quasi-Four-Frequency Zeeman Laser Gyroscopes

The research conducted in this work, was aimed at finding conditions that suppress the influence of the magnetic field on zero drift in Zeeman four-frequency and quasi-four-frequency laser gyroscopes. We determined the optimal areas within the gain contour in the active medium. During operation in those areas the maximum suppression of the influence of the magnetic field on the drift of the gyroscope is provided. A gyroscope control system that switches gyroscope to the regime of minimum magnetic sensitivity has been created. We obtained weakening of the effect of the magnetic field on zero drift by more than three orders of magnitude.
