| Abstract: | The dynamic and stationary equations for a bragg acousto-optic bistable system with a delay in the feedback loop have been derived. The parameters for bistability were analysed and the boundary for instability was given. The regularity of the change of the unstable oscillation wave form and the structure of the power spectrum were analysed. |
