Abstract

We propose a simple quasi-phase-matching (QPM) scheme in high-order harmonic generation (HHG) based on the approximately linear dependence of the phase mismatch on harmonic order. With this scheme, essentially all the harmonic orders are phase matched simultaneously, with harmonic order q experiencing a qth-order QPM. We validate this proposal by simulations using a semiclassical numerical model of HHG.
