Abstract

The non-reciprocal bias element necessary for operation of a four-frequency differential ring laser gyroscope (RLG) is the subject of this paper. Each of the three alternative bias approaches currently under consideration, namely, Zeeman bias, a magnetic mirror, and a Faraday cell, is discussed in the context of its effect on the performance of a RLG. Relevant results of a detailed model including cross-relaxation, Zeeman effect, hole-burning, pathlength controller operation, and temperature are given.
