摘要
本文从理论上计算及分析了带有延时反馈回路的Bragg型声光双稳系统的双稳特性及非稳特性。由系统的动力学方程、稳态方程出发,给出了出现双稳态的参数范围。计算并绘出了非稳区域边界,分析了非稳振荡波形变化规律及其模结构。
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.
