Abstract

Several years ago Ezekiel proposed and built a passive ring laser gyroscope whereby laser light is injected into an optical cavity via an external source'. The passive approach has potentially several advantages over the active ring gyro, as has been pointed out by Ezekiel and others 2,3,4. Among them are elimination of Langmuir flow effects and elimination of magnetic field sensitivity. When considering the passive RLG it might appear that it should not exhibit the beat frequency locking phenomenons. We wish to point out that at least under some conditions, the passive gyro should show locking behavior.
