Abstract

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