A six-level inverted-Y scheme is proposed for elucidating the effect of hyperfine levels on the behavior of the two-dimensional (2D) and three-dimensional (3D) atom localization. An analytical model based on density matrix technique demonstrates that the information about atom’s position can be readily extracted by measuring the spatial optical absorption. We find that the presence of several excited states in inverted-Y interaction considerably alters the localization profiles as compared to the four-level approximation. Under suitable parametric conditions, we attain nearly 100 probability of detecting atom at particular position in 2D and 3D subspaces. Such efficient and high precision 2D and 3D atom localization may have potential applications in laser cooling and atom nanolithography.
