Abstract
In a study concerned with second-harmonic generation at grating couple rs, Kull et al. [Opt. Lett. 16, 1930 (1991)] observed a curious phenom enon in which the second-harmonic efficiency exhibits dips, instead of peaks, when the angle of incidence of the pump beam is scanned throug h its resonant value. This surprising result has not been explained. I t is our aim to show that this effect is closely related to the existe nce of nonlinear zeros.
