“…The frequency pulling in that study was found to be confined to a small region around the free-running frequency. A pushed stable locking range was observed when two masters were injected simultaneously [11]. The direction of this pushing was found to be toward the negative detuning frequency with a low injection ratio.…”

“…Although frequency pulling has been studied widely in lasers, there are not many cases of frequency pushing studies. Most of the frequency pushing measurements were done in free space [14][15][16]. Only one study was carried out with a vapor cell placed in a cavity [17].…”

We observed the frequency pushing of the cavity resonance as a result of the coupling of the cavity field with the ground state 138Ba in a high-Q cavity. A weak probe laser propagated along the axis of a Fabry-Pérot cavity while ground-state barium atoms traversed the cavity mode perpendicularly. By operating the atom-cavity composite in the vicinity of an exceptional point, we could observe a greatly enhanced frequency shift of the cavity transmission peak, which was pushed away from the atomic resonance, resulting in up to 41±7 kHz frequency shift per atom from the cold cavity resonance. We analyzed our results by using the Maxwell-Schrödinger equation and obtained good agreement with the measurements.
