Modeling Fast Modulation Effects in Cesium Atomic Clocks

Abstract

A theory for fast modulation in cesium frequency standards has been developed and expressions derived for frequency offsets produced by Rabi and cavity pulling with square-wave phase modulation. These are compared with equivalent expressions for sine-wave phase modulation. Ratios of the amplitudes of the frequency offsets in the two modulation schemes are calculated for a mono-velocity beam and shown to be in agreement with measurements performed on a commercial standard. This analysis allows a more complete evaluation and comparison of different modulation schemes for cesium atomic beam standards.
