We analyze numerically the dynamics of optical patterns in a photorefractive single feedback system where a vortex beam is used as the input beam. Depending on the topological charge of the vortex and on the nonlinear photorefractive coupling strength, we observe different pattern geometries with a rotating dynamics.
我们数值分析了光反馈系统中光模式的动力学,其中采用涡旋光束作为输入光束。根据涡旋的拓扑电荷和非线性光折变耦合强度,我们观察到具有旋转动力学的不同模式几何形状。
