We report experimentally on extreme events in the pulsating dynamics of an optical time-delayed system, i.e., a diode laser subject to a phase-conjugate feedback. We study the effect of the feedback strength on extreme events' properties. We show a transition to non-Gaussian statistics of the pulse intensity and an increased number of extreme events as the mirror reflectivity increases. The extreme event pulse is anticipated and followed by smaller pulses with time-delay periodicity.
我们在光学时滞系统的脉动动力学的极端事件方面进行了实验研究，即受到相位共轭反馈的二极管激光器。我们研究了反馈强度对极端事件特性的影响。我们表明，随着反射率的增加，脉冲强度的非高斯统计和极端事件数量的增加会发生转变。极端事件脉冲可以被预测，并随后出现具有时滞周期性的较小脉冲。
