We present a theoretical analysis, analytical and numerical, of the oscillation regimes for the semi-linear photorefractive oscillator beyond the instability threshold. This analysis includes the limiting cases of dominating transmission and reflection gratings as well as the cases of spontaneous violation of the frequency degeneracy between the oscillation and pump waves.
