我们研究数值流氓波耗散系统中，作为一个例子，单向光纤激光器在非平稳制度的操作。特定参数集的选择允许激光器产生具有随机分布的峰值幅度的混沌脉冲序列。强度最大值的概率密度函数在较高强度处具有升高的尾部。我们已经发现，在这种设置中产生极端脉冲的概率高于迄今为止所考虑的任何其他系统。
We study numerically rogue waves in dissipative systems, taking as an example a unidirectional fiber laser in a nonstationary regime of operation. The choice of specific set of parameters allows the laser to generate a chaotic sequence of pulses with a random distribution of peak amplitudes. The probability density function for the intensity maxima has an elevated tail at higher intensities. We have found that the probability of producing extreme pulses in this setup is higher than in any other system considered so far.
