Abstract
A laser gyro having a solid-state amplifying medium and an optical ring cavity includes an assembly encompassing the optical cavity and able to experience an oscillating rotational motion, as well as at least one external optical device for longitudinal injection of energy into the solid-state amplifying medium. The laser gyro also includes 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.
Claims7
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.
