A new arrangement of an electromagnetically induced grating in a three-level Ladder-type atomic system with indirect incoherent pumping field is proposed. It is found that the diffraction intensity can efficiently be controlled by the spontaneously generated coherence (SGC). In addition, the diffraction intensity spectrum can dramatically be tuned by manipulating the coupling field intensity, resonance conditions, the rate of an indirect incoherent pumping field, and interaction length.
