Abstract
A laser gyro includes an amplifying solid element and a device for vibrating said amplifying solid element at a predetermined frequency, along an axis of revolution of said amplifying solid element. The geometry of said amplifying solid element is such that a natural mode of mechanical vibration of said amplifying solid element corresponds to said predetermined frequency.

A laser gyro, comprising:
- an amplifying solid element, and
- a device for vibrating said amplifying solid element at a predetermined frequency f, along an axis of revolution of said amplifying solid element,
- wherein the geometry of said amplifying solid element is such that a natural mode of mechanical vibration of said amplifying solid element corresponds to said predetermined frequency f and to the direction of the axis of revolution of said amplifying solid element, said frequency f of vibration is the frequency of the first natural mode of axisymmetric vibration of said amplifying solid element along the direction of propagation of the optical waves of the laser gyro.
A method for vibrating an amplifying solid element, comprising:
- vibrating said amplifying solid element at a predetermined frequency f, in the direction of the axis of revolution of said amplifying solid element,
- wherein said amplifying solid element is designed so that a natural mode of vibration of said amplifying solid element corresponds to said predetermined frequency f and to the direction of the axis of revolution of said amplifying solid element, said frequency f of vibration is the frequency of the first natural mode of axisymmetric vibration of said amplifying solid element along the direction of propagation of the optical waves of the laser gyro.
