We study the influence of noise in the dynamics of a laser with optical feedback. For appropriate choices of the feedback parameters, several attractors coexist, and large enough noise induces jumps among the attractors. Based on the residence times probability density, it is shown that with increasing noise the dynamics of attractor jumping exhibits a resonant behavior, which is due to the interplay of noise and delayed feedback. It is also shown that this type of resonance is not specific to the model equations used, since it also occurs in other delay differential equations.
我们研究了光学反馈对激光动力学中噪声的影响。对于反馈参数的适当选择，多个吸引子共存，并且足够大的噪声会导致吸引子之间的跳跃。基于驻留时间概率密度，结果表明，随着噪声增加，吸引子跳跃动力学呈现出共振行为，这是噪声和延迟反馈相互作用的结果。还表明，这种共振类型并非所使用的模型方程所特有，因为它在其他延迟微分方程中也会出现。
