"Conditions for optical parametric oscillation with a structured light pump"

Dr. Gabriel Bie Alves , Universidade Federal Fluminense, Brazil
[Host: Olivier Pfister]

We investigate 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-linear interaction. These rules imply a hierarchy of oscillation thresholds that determine the possible transverse modes generated by the OPO, as remarkably confirmed with experimental results.
