ABSTRACT:
A ring laser gyro uses a composition for the gain medium which optimizes the effect of the Fresnel-Fizeau drag on the output signal of the gyro. In one embodiment, a composition of the gain medium is used which produces no change in the Fresnel-Fizeau component of the output signal as the discharge current varies from a nominal amount. In another embodiment, a gain medium composition is used which eliminates the Fresnel-Fizeau component of the output signal at a predetermined level of discharge current.
