Abstract
An embodiment of the invention enhances the rotation sensitivity and decreases the dead band width of a standard HeNe ring laser gyroscope (RLG), with the highest enhancement at low rotation rates. The addition of a gas with nuclear spin to the traditional HeNe gain medium is used to create the intracavity gain medium with an anomalous dispersive quality and thus enhanced rotation sensitivity.
