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.

在此，我们提出一种在λ型三能级原子介质中实现二维原子定位的方案，以使原子与两个正交的驻波场和一个探测场相互作用。由于原子在空间上的相互作用，因此可以通过首次监视弱探测场的探测透射光谱来获得有关原子位置的信息。在一个波长域中观察到一个和两个尖锐的局部峰。从理论上讲，我们在小于λ / 25λ / 25的区域内归档了高分辨率和高精度原子定位。结果可能在纳米光刻技术和先进的激光冷却技术中具有潜在的应用。
