Theoretical model of an atomic line filter based on the combination of a double selective pump

Zhenyu Zhu, Hanyang Li, Weimin Sun +1 more

We present a model of an atomic filter based on laser-induced optical anisotropy that is achieved by the combination of a double selective pump. Most of these kinds of atomic optical filters reported previously adopt only one pump to make the atoms populate on particular sublevels. In this paper, another pump is added to the filter system to make sure all the atoms are in the pump–probe cycle. The feasibility of the re-pump is analyzed by employing the rate equation, and the contribution of the re-pump to the filter is discussed under various conditions. Simulation results show that the re-pump can not only enhance the transmission of the filter, but also vary the transmission spectrum peak wavelength.

Narrowband tunable filter based on velocity-selective optical pumping in an atomic vapor

Alessandro Ceré, Valentina Parigi, Marta Abad +3 more

We demonstrate a tunable narrowband filter based on optical-pumping-induced circular dichroism in rubidium vapor. The filter achieves a peak transmission of 14.6%, a linewidth of 80 MHz, and an out-of-band extinction of >or=35 dB. The transmission peak can be tuned within the range of the Doppler linewidth of the D1 line of atomic rubidium at 795 nm. While other atomic filters work at frequencies far from absorption, the presented technique provides light resonant with atomic media, useful for atom-photon interaction experiments. The technique could readily be extended to other alkali atoms.

Atomic filter with large scale tunability

Shuangqiang Liu, Yundong Zhang, Hao Wu +1 more

We propose an atomic filter configuration with large tunability based on selective optical-pumping-induced anisotropy. Theoretical simulation shows that the filter structure, by using a counterpropagating pump, can achieve higher transmission and a narrower passband than that using a copropagating pump due to the elimination of Doppler broadening. In addition, the filter’s tunability over 100 GHz via Aulter–Townes splitting and filtering characteristics is analyzed.
