HeNe ring-laser gyros are standard sensors in inertial guidance; mirror reflectances now reach 99.9999%. Present research instruments have an area of , a passive quality factor of , and a resolution of the frequency difference of counter-rotating optical beams approaching microhertz. In the Sagnac effect, this difference is proportional to the angular velocity. Present resolution is limited by thermal drifts in frequency pulling, itself reflecting mirror backscatter. The capability of ring… 
Analysis of ring laser gyroscopes including laser dynamics
Inertial sensors are important at application level and also in fundamental physics. Ring laser gyroscopes, which measure angular rotation rates, are among the most sensitive ones. Large area ring
Ring Laser Measurements of Ground Rotations for Seismology
Abstract Since the discovery of the wave nature of light, optical interferometry has assumed an important place in high precision metrology. This is mostly due to the inherent high sensor resolution
Perspectives for Ring Laser Gyroscopes in Low-Frequency Seismology
Variations in the ring laser signal of the rotating Earth are caused by local rotations and by north–south tilts. Analytic expressions for the computation of synthetic seismograms for ring lasers
Novel Progress in the High-sensitivity Heterolithic Ring Laser Gyroscope Technology
The sensitivity achieved by large ring laser gyroscopes opens the perspective to observe in an Earthlocated laboratory extremely small effects expected from fundamental theories of physics. The
Large ring lasers: beyond the Macek and Davis experiment.
Large-scale ring laser gyroscopes are highly sensitive rotation sensors whose operating principle is based upon the Sagnac effect. They are constructed for direct measurement of Earth rotation and
Development of a ring laser gyro
Ring laser gyroscopes are inertial sensor based on the Sagnac effect: rotation causes the frequency of the two counter-propagating beam in the ring cavity to be shifted by an amount proportional to
Laser gyroscopes for very high sensitive applications
We present a summary of the recent results obtained with the “G-Pisa” laser gyroscope prototype in the field of rotational metrology. The experimental apparatus consists in an He-Ne laser having a

TLDR
The first experimentally viable proposals to make terrestrial tests of general relativistic effects such as the frame dragging of the rotating Earth are proposed.
On the detectability of the Lense–Thirring field from rotating laboratory masses using ring laser gyroscope interferometers
The possibility of detecting the Lense–Thirring field generated by the rotating earth (also rotating laboratory masses) is reassessed in view of recent dramatic advances in the technology of ring
A Laser gyroscope system to detect the Gravito-Magnetic effect on Earth
Ring lasers are inertial sensors for angular velocity based on the Sagnac effect. In recent years they have reached a very high sensitivity and accuracy; the best performing one, the ring Laser G in
