摘要：
A multioscillator ring laser gyro includes an optical ring cavity, a solid-state amplifying medium and a measurement device arranged in such a way that a first linearly polarized propagation mode and a second linearly polarized propagation mode, perpendicular to the first mode, propagate in a first direction in the cavity and in such a way that a third linearly polarized propagation mode parallel to the first mode and a fourth linearly polarized propagation mode parallel to the second mode propagate in the opposite direction. The amplifying medium is a crystal of cubic symmetry having an entry face and an exit face, the crystal being cut so that said faces are approximately perpendicular to the crystallographic direction, the various modes propagating in directions approximately perpendicular to said faces.
