Abstract:
1. A solid-state gyrolaser comprising: at least one optical cavity in which two counter-propagating optical modes can propagate in opposite direction to one another, and a device for stabilizing intensities so as to maintain equilibrium of the two counter-propagating modes having at least, inside the optical cavity, an optical assembly comprising: the device for stabilizing the intensities having: a means for measuring the control command, a means for storing a behaviour model of a frequency bias induced by the device for stabilizing the intensities, as a function of the control command, a means for calculating the frequency bias induced by the device for stabilizing the intensities, on the basis of a value of the control command and the model, a means for calculating a bias in the rotation measurement induced by the frequency bias, and a means for compensating for the bias in the rotation measurement.
