Abstract

We study Čerenkov-type second-harmonic generation in a two-dimensional quasi-periodically poled LiNbO₃ crystal. We employ a new geometry of interaction to observe simultaneous emission of multidirectional nonlinear Čerenkov radiation with comparable intensities. This opens a way to control the angle of Čerenkov emission by tailoring the nonlinearity of the material, which is otherwise intrinsically defined by dielectric constants of the medium and their dispersion.
