title: Instabilities and self-pulsation in a ring cavity with a photorefractive wave mixer.
abstract: We find instabilities and self-pulsation in an optical ring cavity with a photorefractive two-wave mixer. The mean field limit is used to obtain a single criterion for instabilities that originate from a Hopf bifurcation.
