Because of the importance of second harmonic generation (SHG) in some nonlinear media, in this paper, we investigated induced SHG in diamond where there is no intrinsic second-order susceptibility, [Formula: see text]. The electric field is proposed to introduce moving susceptibility of the second-order and induce second harmonic generation. Then, spatiotemporal quasi-phase matching (QPM) is applied to optimize the induced SHG. Numerical results reveal that in this way, the induced second harmonic is found at the frequency of [Formula: see text] rather than [Formula: see text].
