    "abstract": "We demonstrate that first-order light-shifts can be cancelled for an\nall-optical, three-photon-absorption resonance (\"N-resonance\") on the D1\ntransition of Rb87. This light-shift cancellation enables improved frequency\nstability for an N-resonance clock. For example, using a table-top apparatus\ndesigned for N-resonance spectroscopy, we measured a short-term fractional\nfrequency stability (Allan deviation) 1.5e-11 tau^(-1/2) for observation times\n1s\u003c tau \u003c 50s. Further improvements in frequency stability should be possible\nwith an apparatus designed as a dedicated N-resonance clock.",
