Paper Abstract
We have measured the dispersion for a 632.8nm probe beam in helium neon vapor in the presence of a strong pump. Our
measurements show an average index of refraction variation of 1.27 * 10-6 per GHz. This degree of dispersion could
provide up to a 33% scale factor enhancement if implemented in a Ring Laser Gyroscope (RLG), and our measurements
indicate enhancements of >100% are possible. With some modifications in this approach, the same dispersion should be
achievable in a compact system which can be integrated with existing RLGs at a reasonable cost and without drastic
increases in size, weight, or power. Further theoretical modeling is required in order to determine the maximum
achievable scale factor enhancement, and the effects on rotational measurement noise and bias stability.
