Description
Summary:The paper is devoted to the current problem of increasing the accuracy of magneto-optical laser gyros while maintaining their stable operation in real operating conditions. The problem is considered and studied by the example of the magneto-optical Zeeman laser gyroscope, which is one of the effective types of laser gyroscopes. The development and improvement of the technology for creating this type of gyroscopes makes it possible to significantly reduce the sources of the gyroscope zero drift and yet, retain the other properties and performance parameters. The study and validation of the possibility of a significant reduction in the gyroscope key control currents, such as the pumping currents of the active medium and the control currents of frequency bias, will increase the measuring accuracy of the gyroscope and, accordingly, the accuracy of navigation systems based on them.
