Multifrequency YAG:Cr4+ Solid-State Laser Gyroscope, Perimeter Control and Dither Creation System, Operating Regimes

We present a results of a study on a creation of a multifrequency solid-state laser gyroscope based on a broadband YAG:Cr
⁴⁺
active medium. The gyroscope uses mode locking for improved accuracy and noise suppression. A significant reduction in the spectral width of the longitudinal modes beat signals and an improvement in the accuracy due to mode locking is proved both theoretically and experimentally. Additional methods for stabilizing the lasing frequency of a ring laser gyroscope in multifrequency regime using a frequency standard and a saturable absorber are presented. A method for creating a frequency bias based on an electro-optical modulator is considered.
