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].

Applying a bicolor coherent treatment of a Nd-YAG laser with wavelength 1.32 μm and its second harmonic generation, we have investigated photoinduced SHG in Au nanoparticledeposited ZnO nanocrystallinne (NC) films. We have established that coexistence of the such crystallites gives substantially better results compared to the pure ZnO NC deposited onto the glass substrate. It was shown that the value of the second order susceptibility obtained for the large incident angles of the fundamental and writing beams is equal to about 23 pm/V. The better results are obtained during the phototreatment at temperatures near the 60 oC for the Au doped samples and is almost non-sensitive to temperature for the pure samples. The further increase of the temperature leads to decay of the optical second harmonic generation
