Abstract:
1. A laser gyro having a solid-state amplifying medium and an optical ring cavity, comprising: an assembly encompassing the optical cavity and able to experience an oscillating rotational motion; at least one external optical device for longitudinal injection of energy into the solid-state amplifying medium; and a fixing assembly adapted for translationally and rotationally binding said assembly encompassing the optical cavity and said external optical device for longitudinal injection of energy; wherein, the at least one external optical device for longitudinal injection of energy further comprises an energy source, a spherical mirror translationally tied with said fixing assembly, a first concave planar or convex planar lens disposed between said energy source and said spherical mirror, and a second concave planar or convex planar lens disposed between said spherical mirror and the corresponding partially reflecting mirror; the portion of the fixing assembly serving as support for said spherical mirror is tilted by substantially 45° with respect to the incident energy beam and is tilted by substantially 45° with respect to the energy injection reflected beam.
