Research output: Contribution to conferencePaperpeer-review


This work provides details about the different scenarios that arise when diffractive effects cause the homogeneous profile of the signal and idler waves of optical parametric oscillators (OPO) to become unstable. The model couples the second-order nonlinearity of OPO with diffraction by considering free propagation of light in the cavity. The lowering of the OPO threshold for the nondegenerate case is discussed and the spatiotemporal dynamics associated with the presence of rolls in the transverse plane is also studied. Irregular and turbulent behaviours are found for pump intensities far above the threshold of generation of the signal and idler waves.
