A push-pull method of controlling a laser gyro comprising at least three mirrors for implementing a closed loop light path for two laser beams propagating in opposite directions, the gyro also being subjected to dither movement, at least two mirrors being associated with respective actuators connected to push-pull control members for controlling the positions of the mirrors so as to minimize the amplitude of a winking signal occurring in a lased intensity signal of the laser beams, the method comprising the steps of detecting the frequency of the winking signal of at least one laser beam, and of triggering measurement of the amplitude of the winking signal when the frequency of the winking signal is less than a predetermined threshold corresponding to passing into a dead band of the gyro.
