Investigation results of angular structure formation in a picosecond traveling-wave optical parametric generator (OPG) based on a KDP crystal (type II phase matching) pumped by intersecting beams are presented. It is demonstrated that the angular structure of the OPG output radiation is controlled by pump geometry. Frequency-tuned diffraction-limited output even in a single-pass OPG was observed.
