Power Dependence of the Frequency Bias Caused by Spurious Components in the Microwave Spectrum in Atomic Fountains

Abstract

The presence of spurious spectral components in the microwave excitation may induce frequency shifts in an atomic fountain. We discuss how such shifts behave as a function of power variations of the excitation carrier and in the spur-to-carrier ratio. We find an extremely rich and unintuitive behavior of these frequency shifts. We also discuss how pulsed operation, typical of today¿s fountain frequency standards, relates to frequency shifts caused by spurs in the microwave spectrum.
