Paper Abstract

Errors of a miniature Zeeman ZLK-16 RLG, caused by the coupling of countrary waves, are considered. A models of such a coupling effects, based on the radiation backscattering at the resonator mirrors, shows the way to minimize lock-in and accompanying errors without high upgrade of RLG mirrors technology. Resonator geometry parameters, that make effect on the coupling level, are presented, and thus provide a means for coupling minimization by the control of ring cavity geometry. The application of such method for ZLK-16 RLG design, referred at the article, shows that such method of coupling minimization is significant to decrease irreproducible components of laser gyro errors, especially turn-to-turn repeatability and scale factor stability.
