Abstract

We demonstrate that first-order light shifts can be canceled for an all-optical, three-photon-absorption resonance (N-resonance) on the D1 transition of Rb87. This light-shift cancellation facilitates improved frequency stability for an N-resonance clock. For example, by using a tabletop apparatus designed for N-resonance spectroscopy, we measured a short-term fractional frequency stability (Allan deviation) of 1.5×1011τ12 for observation times of 1sτ50s. Further improvements in frequency stability should be possible with an apparatus designed as a dedicated N-resonance clock.
