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.
我们对耗散系统中的 rogue 波进行了数值研究，以处于非平稳运行状态的单向光纤激光器为例。特定参数集的选择使激光器能够产生具有随机峰值幅度分布的混沌脉冲序列。强度最大值的概率密度函数在较高强度处有一个升高的尾部。我们发现，在这种设置下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。
