A quasi phase matched structure with a period A is also periodic at an integer multiple (m) of A. Suppose we use this higher order grating for quasi phase matching in a second harmonic generation experiment. As a simple estimate, what do you expect the ratio of the second harmonic field at the output for an m-order grating is, compared to the case when m=1: O 1/m² Om m² O 1/m
