Abstract

We develop a three-level theoretical model for atomic optical filters based on optical anisotropy induced by the circularly polarized pump field. Calculative results are in good agreement with experimental results reported previously [Opt. Lett 27, 500 (2002) ]. The filtering characteristics such as the functions of pump intensity, pump detuning, and cell temperature are studied, respectively. The theoretical analysis presented here is expected to be useful in investigating atomic optical filters and polarization spectroscopy.
