Abstract

Rb vapor cell produced results in good agreement with our numerical simulation. This work provides a novel and simple means to manipulate phase sensitive electromagnetically-induced-transparency or four-wave mixing, and could be useful for applications in quantum optics, nonlinear optics and magnetometery based on such systems.

Suppression of four-wave mixing in hot rubidium vapor using ladder scheme Raman absorption

Nikunj Prajapati, G. Romanov, Irina V. Novikova

We experimentally investigate the effectiveness of four-wave mixing suppression in a double-Λ interaction scheme by introducing an additional ladder-type two-photon Raman absorption resonance for one of the optical fields. We propose several possible interaction configurations involving either one or two isotopes of Rb and experimentally demonstrate the possibility of efficient four-wave mixing suppression in both electromagnetically induced transparency and far-detuned Raman cases.

By analyzing the relative frequencies and amplitude of multiple electromagnetically induced transparency resonances in external magnetic field, we achieve scalar magnetometer sensitivity <5pT/Hz, and can determine the B-field direction with angular sensitivity < 1° using machine learning and optical lock techniques in a 100 mm3 atomic vapor cell.

Slow light propagation and amplification via electromagnetically induced transparency and four-wave mixing in an optically dense atomic vapor

Nathaniel B. Phillips, Alexey Vyacheslavovich Gorshkov, Irina V. Novikova

We experimentally and theoretically analyze the propagation of weak-signal field pulses under the conditions of electromagnetically induced transparency (EIT) in hot Rb vapor, and study the effects of resonant four-wave mixing (FWM). In particular, we demonstrate that in a double-Λ system, formed by the strong control field with the weak resonant signal and a far-detuned Stokes field, both continuous-wave spectra and pulse propagation dynamics for the signal field depend strongly on the amplitude of the seeded Stokes field, and the effect is enhanced in optically dense atomic medium. We also show that the theory describing the coupled propagation of the signal and Stokes fields is in good agreement with the experimental observations.

Linewidth of electromagnetically induced transparency under motional averaging in a coated vapor cell

Zhi-Xiang Xu, Weizhi Qu, Ran Gao +2 more

The linewidth of electromagnetically induced transparency (EIT) in a coated Rb vapor cell was studied under a magnetic field gradient. The nonlinear broadening of the EIT linewidth with the magnetic field gradient was observed. It was found that the motional averaging of the field gradient was more pronounced at higher laser intensities and larger beam sizes. In the same regime, there was a small linewidth decrease with the increasing magnetic field gradient. We have established a Monte-Carlo model, which gave results in good qualitative agreement with our experiment. Physics pictures for the above phenomena were also suggested. These results provide an understanding of the EIT linewidth behavior under motional averaging, and should be useful for applications in quantum optics and metrology based on coated vapor cells.
