摘要

The field of the invention is that of the solid-state laser gyros used for the measurement of the speeds of rotation or the relative angular positions. This type of equipment is used in particular for aeronautical applications. The object of the invention is to be completed in the optical devices required for control of the instability of the lasers with specific optical devices making it possible to eliminate the blind zone. It is thus obtained a solid state laser "all-optical" without moving parts, stable and without aveugle.a this purpose, the laser gyro according to the invention comprises, in particular: an optical assembly (5) which makes it possible to introduce a non-reciprocal phase shift between the optical modes against - propageants; the control means (6), making it possible to vary the amplitude of the phase shift of a periodic manner around a mean value is very substantially zero.
