We develop an effective numerical algorithm to design engineered quasi-phase-matching gratings in nonlinear crystals for the parametric generation of harmonics of arbitrary order from a fundamental frequency input. We use the method to design and numerically demonstrate a lithium niobate parametric generator excited by a continuous-wave source in the regime of pump depletion.
