Abstract
A method for compensating a reference frequency shift due to an interaction of resonant light provided by a resonant light source with atoms of an atomic beam crossing a resonant microwave cavity between light interaction zones includes toggling a wavelength of the provided resonant light between a main optical pumping transition, OPT, and an alternate optical pumping transition, OPT, of the atoms of the atomic beam while a frequency of the microwave probe signal fed into the microwave cavity is modulated with a frequency modulation depth, FMD. The method further includes computing a wavelength modulation compensation error signal, WM-CES depending on the measured signal amplitudes of Ramsey fringes used to control the frequency of the microwave probe signal fed into the microwave cavity.
