Off-Bragg reconstruction of volume holographic grating is known to result in an attenuation of the diffracted beam intensity. In this letter we demonstrate that contrary to the disseminated believe a strong increase of the diffracted beam intensity can be observed when an angular deviation between the grating and reconstruction beam takes place in the direction perpendicular to the dispersion plane. The effect of such `anomalous' behavior of the diffracted beam intensity is studied experimentally.
