The design and testing of a proof-of-principle triangular active ring laser interferometer ~13 m on a side is discussed. Issues such as lock in, multimode interference, mode hopping, and neon isotope mixtures are examined as they relate to large He–Ne ring lasers. Responses of the ring laser to Earth’s rotation and perturbations that change its tilt or area are presented. Some potential applications are suggested for large interferometers.
