摘要
We investigate high-precision three-dimensional （3D） atom localization in a coherently-driven, four- level atomic system via spontaneous emission. Space-dependent atom-field interactions allow atomic position information to be obtained by measuring parameters, atoms within a certain range can be spontaneous emission. By properly varying system localized with nearly a probability of 100% and a maximal resolution of -0.04λ. This scheme may be useful for the high-precision measurement of the center-of-mass wave functions of moving atoms and in atom nanolithography.
