Abstract ：We investigate the behavior of two-dimensional (2D) atom localization in a three-level cascade-type atomic system via measuring the probe absorption. It is found that the precision of the atom localization can be improved by adjusting probe detuning and coupling a coherent coupling field and standing-wave fields to the same atomic transition. Remarkably, a single localization peak can be obtained by adjusting appropriate system parameters, and some corresponding explanations are also given.
