TLDR
In this article, a nonplanar active ring laser cavities and their uses for the gyro builder are discussed and it is shown how a slightly non-planar configuration may create magnetic sensitivities and how they may be controlled.Abstract:
Nonplanar active ring laser cavities and their uses for the gyro builder are discussed and it is shown how a slightly nonplanar configuration may create magnetic sensitivities and how they may be controlled. Another origin of magnetic biases in both square and triangular ring laser gyros, namely stress-induced linear birefringence in the gyro mirrors, is examined and possible experimental arrangements for measuring the size of birefringences produced by stress in mirrors suggested.read more

The ring laser gyro
M Faucheux,D Fayoux,J J Roland +2 more
TL;DR: In this article, the authors recall the basic principles and advantages of the ring laser gyro (RLG) which is the most widely developed of all optical gyroscopes based on the Sagnac effect.

Optical measurement with direct traceability to the primary standards of length and time: toward a system of metrology based entirely on the properties of the photon
TL;DR: In this paper, it is proposed that the primary standards of length and time have now reached a sufficient level of maturity that they can be removed from the standards laboratories and used directly for measurement calibration with minimal recourse to the use of intermediate secondary standards.

Polarization modeling in square ring resonators with the consideration of output mirror's stress effect
TL;DR: In this paper, a polarization model for calculating the ellipticities of the clockwise and counter-clockwise output beams in square ring resonators is established, which takes into account the following parameters such as Ar, g, ξ and Φ simultaneously, where Ar is the distortion angle, g is the phase shift of all four mirrors, and ξ is the angle between the S-polarization and the substrate "fast" axis of the output mirror.

Practical method for eliminating the magnetic bias sensitivity of square ring laser gyros by adjusting the nonplanar angle
TL;DR: In this article, the magnetic bias sensitivity of a square ring laser gyroscope has been shown to be almost constant for this kind of laser gyros, which is useful for the practical elimination of the bias sensitivity.

A compact super sensitive nonplanar ring laser magnetometer
TL;DR: In this paper, a ring laser magnetometer with the wavelength at 632.8nm is proposed. But the magnetometer is not a ring-laser gyroscope.
