In this article the study of the multifrequency generation regime in a laser gyroscope was undertaken. The study is performed on a laser gyroscope with a broadband solid-state wide-range active medium YAG:Cr4+ and a gyroscope on a semiconductor optical amplifier and with a fiber-optic cavity. Mode-locking was used in order to improve stability and reduce noise. Using Lamb theory-based equations, a mathematical model of the bi-directional generation dynamics in a gyroscope in the mode-locked for multifrequency generation in a laser was developed. The loss modulation phase and depth influence on the value of the stable mode synchronization area, as well as the generation parameters ensuring the registration of the angular quantities with maximum accuracy are defined.
