In this paper, we study the dynamical decoupling method for suppressing the decoherence of a Δ-type three-level atom. We consider a realistic situation that the pulse length of radio-frequency pulse (RF pulse) is finite. A dynamical decoupling group is given for designing the RF pulse sequences. Our analytical results show that the corresponding decoupling operations can suppress the decoherence completely in ideal conditions. In the realistic situation, the numerical results indicate that the decoherence can also be suppressed effectively.
