Abstract

Abstract: Herein, we propose a scheme for the realization of two-dimensional atomic localization in a λ -type three-level atomic medium such that the atom interacts with the two orthogonal standing-wave fields and a probe field. Because of the spatially dependent atom-field interaction, the information about the position of the atom can be obtained by monitoring the probe transmission spectra of the weak probe field for the first time. A single and double sharp localized peaks are observed in the one-wavelength domain. We have theoretically archived high-resolution and high-precision atomic localization within a region smaller than λ /25 × λ /25. The results may have potential applications in the field of nano-lithography and advance laser cooling technology.
