Abstract

This article focuses on improving the long-term frequency stability of the vapor-cell Rubidium Atomic Frequency Standard (RAFS) by actively compensating for frequency variations induced by temperature changes in the lamp oven and cavity oven. The proposed method uses light intensity variations, which correlate with frequency deviations via the light-shift effect (LSE), to regulate the current in the C-field coil through a feedback circuit, thereby reducing temperature sensitivity. Experimental results demonstrate that this approach significantly lowers the lamp oven and cavity oven temperature sensitivities and enhances the RAFS's long-term frequency stability, making it a viable technique for optimizing rubidium atomic clock performance.
