SMALL RING LASER Russian patent published in 2024 - IPC G01C19/70 H01S3/83 

FIELD: gyroscopic measuring technology.

SUBSTANCE: small-sized ring laser, including a housing with a hole for mounting on a vibration suspension, a vibration suspension, a planar optical resonator, information and power photodetectors, a piezoelectric transducer and a mixing prism, while inside the housing there is a main channel running along the perimeter of the housing, and reflective elements are installed on the side faces of the housing elements communicating with the main channel through sinuses, at least one reflective element has a prism installed on which at least one photodetector is installed, a piezo motor is installed on at least one reflective element, and one cathode and two anodes are installed on the side faces of the housing, one of which is an anode-rod, and the said one cathode and two anodes communicate with the main channel through sinuses, while the channels in the body of the planar ring optical resonator, through the centre of which counter-propagating electromagnetic waves propagate, have a stepped shape, and the diameter of the passive part of the channel is greater than the diameter active part by at least 20%, and the distance of the anodes from the cathode is maximum.

EFFECT: increasing the accuracy of the useful signal.
