Abstract

A He–Ne ring laser has given the Earth-rotation-induced Sagnac frequency to a precision of 1 μ Hz, or 2 parts in 10⁸, 2 × 10^-21 of the laser frequency. Because the beat frequency in a ring laser originates in either timereversal or (with a more complicated polarization geometry) parity-violating effects, such systems have the potential of detecting ultrasmall symmetry violations.
