摘要

The dependence of multi-frequency second-harmonic generation efficiency on the fluctuation in the angle between the interacting waves in the two-dimensional aperiodic optical superlattice is investigated in this paper. It is found that the efficiency of second-harmonic generation is a function of parameters that have an essential and critical role in maintaining the phase-matching condition, one of which is the angle between interacting waves in nonlinear crystal. Applying a comparison between the exact and fluctuated situations in a two-dimensional nonlinear aperiodic optical superlattice causes the output efficiency of the multi-frequency process to be decreased.
