“…The triplet spectrums in different conditions are also given in figure 2, where the first three show how the triplet spectrum varies with the initial atomic polarization, and the last one shows the triplet spectrum in which only the initial atomic polarization exists and the pumping laser is turned off at t=0. The features of the triplet spectrums are generally consistent with the experiments in [12].…”

“…In our recent works [12,13], we show that, in a nuclear magnetic resonance system, where the ground-state nuclear spin of 3 He is polarized by metastability-exchange optical pumping and resonantly driven by a transverse oscillating magnetic field, the coherence is transferred to the metastable state of 3 He and a triplet spectrum is probed by a circularly polarized laser beam. The central peak of the triplet locates at Larmor frequency, and the sidebands are with an interval of Rabi frequency to the central peak, analogous to the Mollow triplet [14].…”

We present a systematic analysis to explain the observed magnetic resonance spectrum with three or five peaks spaced at Rabi frequency when the metastable 3He atoms are probed with a transverse circularly or linearly polarized 1083 nm laser beam, respectively. The resonance signals are generated in the ground state of 3He atoms, dressed by a resonant magnetic field, and transferred to the metastable state by collisions. The triplet spectrum is thought to be the result of the linear coupling between the metastable state and the ground state, while the quintuplet is thought to be that of the nonlinear coupling, and indicates that higher-order atomic polarization is created during the atomic collisions. More features of the magnetic resonance signals are investigated.

“…Noble-gas NMR sensors use spin-exchange collisions with alkali atoms. Because alkali spins do couple to light, the pickup of the NMR signal can be done optically, and, in this way, narrow spectra and long-lived spin precession signals are routinely obtained (28)(29)(30)(31). Yet, various quantum optics applications require an efficient bidirectional coupling between light and noble-gas spins (32)(33)(34)(35)(36).…”

Nuclear spins of noble gases feature extremely long coherence times but are inaccessible to optical photons. Here, we realize a coherent interface between light and noble-gas spins that is mediated by alkali atoms. We demonstrate the optical excitation of the noble-gas spins and observe the coherent back action on the light in the form of high-contrast two-photon spectra. We report on a record two-photon linewidth of 5 ± 0.7 mHz above room temperature, corresponding to a 1-min coherence time. This experiment provides a demonstration of coherent bidirectional coupling between light and noble-gas spins, rendering their long-lived spin coherence accessible for manipulations in the optical domain.
