Abstract: In condition of quasi-phase-matching,the coupling equations of optical parametrical amplification are solved approximately in this paper,where the depletion of pump is considered.Approximated solution implies that the coupling process oscillates periodically,and the period of oscillation depends on both the coupling coefficient and the pump intensity.The obtained results agree well with numerical simulation.
