摘要
在分岔点附近,通过对描述布拉格(Bragg)型声光双稳系统的差分-微分方程进行线性稳定性分析,得到了系统对小信号放大时的共振频率,给出了放大倍数的表达式。然后通过数值计算模拟出系统对小信号的放大过程。
Near the bifurcation point, the linear stability of difference
differential equation which describes acoustooptic bistable systems is analyzed, the
expression of resonance frequency and amplification multiple are given. The amplification
process of small signal is simulated by numerical calculation, the simulation result is
consistent with theoretical analysis.
