LASER GYROSCOPE Russian patent published in 2018 - IPC G01C19/66 

FIELD: laser engineering.

SUBSTANCE: invention relates to the field of laser technology and can be used in the creation of navigation systems, in particular free-of-charge inertial navigation systems. Optical radiation source is located outside the optical contour of the monoblock in the corresponding seat and is fixed mechanically, and bi-directional mode of its radiation is achieved by applying an optical signal through a specially created optical channel of the laser radiation source to an external optical splitter in the form of a triangular metallic or optically transparent prism. Polished equal side faces of the triangular prism are covered with a reflective coating and form an operating angle at the apex of 89-91°, and the prism itself is placed in the corresponding seat of the monoblock and covers by its working edges 94-96% of the diameter of the additionally created optical channel for pumping the optical contour of the monoblock, which is made parallel to one of the optical channels of the monoblock and interacts with the mirrors of the total reflection of the radiant energy. As a result, the bi-directional optical signal is directed to the aperture of the conjugated optical channels of the optical contour of the monoblock, and the resonators of the conjugation zones are multiply increased in relation to their base size. In this case, the source of laser radiation, laser source channel and the external optical splitter are on the main axis of symmetry of the laser gyroscope.

EFFECT: technical result is a decrease in the temperature instability of the device, increasing the efficiency of using the radiant energy of a semiconductor laser by using an external optical splitter with a fission factor of 0,5, which additionally provides the isolation of the optical contour of the gyroscope with the pumping channel of radiant energy and, as a result, provides a more highly stable performance of the device.
