COMPACT RING LASER Russian patent published in 2024 - IPC G01C19/70 

FIELD: measurement.

SUBSTANCE: invention relates to gyroscopic measurement equipment. Disclosed is a small-sized ring laser, including a vibration suspension and a planar optical resonator, consisting of a housing, in which a hole is made for mounting on the vibration suspension, wherein the connection of the housing of the planar optical resonator and the vibration suspension is performed by gluing together in separate segments not subject to mechanical deformation, wherein the fastening seam is provided with a gap with size of 0.03–0.04 mm along each of the segments between the outer diameter of the vibration suspension and a hole diameter in the housing of the planar ring optical resonator, and the surface roughness is not less than Ra 0.80.

EFFECT: high accuracy of the useful signal of a ring laser at low temperatures.
