【 摘 要 】

We investigate the localization of the four-level V-type atom inside a classical standing-wave field through the absorption spectrum of the weak probe field. The expression of the probe absorption spectrum is derived analytically via perturbation treatment of a weak probe field. Numerical results and discussion of the probe susceptibility spectrum behaviour via non-perturbation treatment of the density matrix elements to all orders of fields are obtained. We have shown that the precision of localization of the atom is dependent on the dephasing rates of atomic coherence as well as on some parameters of the driving and standing-wave fields. A strong localization through sharply peak is achieved at a certain value for the dephasing rates in resonance detunings.
