Abstract

It is shown in Ref. ¹ that the inclusion of the spatio-temporal characteristics of the NL material strongly modifies the stability picture of a single-mode NL optical resonator (as compared to the case of a local and instantaneous material response) under normal incidence. The aim of this paper is to show that these conclusions are strongly affected by the angle of incidence. Indeed the optical transport associated with oblique incidence is found to induce a spatial averaging of the intra-cavity field, which inhibits the emergence of spatial and temporal modulational instabilities (MI).
