Ring laser - Wikipedia
WEBRing lasers are composed of two beams of light of the same polarization traveling in opposite directions ("counter-rotating") in a closed loop. Ring lasers are used most frequently as gyroscopes (ring laser gyroscope) in …
Ring laser gyroscope - Wikipedia
WEBA ring laser gyroscope (RLG) consists of a ring laser having two independent counter-propagating resonant modes over the same path; the difference in phase is used to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation.

The Still Amazing Honeywell Ring Laser Gyroscope
WEBA Ring Laser Gyro (RLG) is a gyroscope that uses the optical Sagnac effect to sense rotation. Most commonly, the RLG is filled with a gas, such as Helium Neon (HeNe), and electrodes are used to excite light waves traveling in the clockwise (CW) and counterclockwise (CCW) directions.
Ring Laser - an overview | ScienceDirect Topics
WEBA Ring Laser is defined as a type of laser that operates in a traveling wave mode, allowing uniform saturation of the gain media. It overcomes limitations of standing wave lasers by enabling single-mode operation and the use of low finesse optics for tuning.
