Influence of stochastic deviations of domain boundary and varying effective index on the conversion efficiency of difference frequency mixing (DFM) in quasi-phase-matching waveguides are analyzed. By simplifying the coupled equations of DFM in waveguide according to the actual situation, we provide analytical expressions of the conversion efficiency for the first time. Four models for random errors...
We analyzed the influence of random deviations of domain boundary in periodically poled crystals on quasi-phase-matching singly resonant optical parametric oscillators (QPM-SROs). A mathematical method of dealing with this matter is proposed and for the first time the functions of quasi-phase-matched singly resonant oscillation's optical power gain and pumping threshold on random deviations are deduced...
