Abstract
We develop a modified version of Ramsey spectroscopy that uses an additional frequency shift to compensate frequency shifts induced by the excitation itself. In its simplest realization, this method uses a small step of the probe frequency during the two Ramsey excitation pulses to provide cancellation. This opens up the possibility of Ramsey spectroscopy even for transitions that have Stark and Zeeman shifts comparable to spectroscopic resolution. In particular optical clocks based on magnetic field-induced spectroscopy, two-photon transitions, or heavily forbidden transitions could benefit from this technique as it enables a new way to evaluate key frequency shifts for these clocks.Citation
