FIELD: physics; optics.
SUBSTANCE: invention relates to solid-state laser gyroscopes used for measuring speed of rotation or angular positions, particularly in aeronautics. Proposed is an optical architecture of a laser cavity based on common maintenance of the scaling factor, temperature stability of which is 4A/λL, where L and A are optical length and area of the laser cavity respectively, and λ is the average wavelength of the laser in Sagnac effect. Each parametre may vary with temperature.
EFFECT: design of a solid-state laser gyroscope with stabilised scaling factor.
