We investig ate the transverse mode structure of the down-converted beams generated by a type-II optical parametric oscillator (OPO) driven by a structured pump . Our analysis focus on the selection rules imposed by the spatial overlap between the transverse modes of the three fields involved in the non-line ar interaction. These rules imply a hierarchy of oscillation thresholds th at determine the possible transverse modes generated by the OPO\, as remar kably confirmed with experimental results.
