The analysis in our manuscript allows explaining two long-standing mysteries in ultrafast laser physics. First, experimentally observed pulse shapes of few-cycle oscillators showed stark deviations from the theoretically expected hyperbolic secants. Second, there were numerous reports on "magic" self-modelocking without saturable absorber mechanism. All these observations defied theoretical predictions. Our frequency-domain approach for using the Haus master equation allows explaining many peculiar findings that have given rise to numerous controversial discussions.

我们手稿中的分析可以解释超快激光物理学中两个长期存在的谜团。首先，实验观察到的少周期振荡器的脉冲形状与理论上预期的双曲正割存在明显偏差。其次，有大量关于不带饱和吸收器机制的“神奇”自锁模的报道。所有这些观察结果都违背了理论预测。我们使用 Haus 主方程的频域方法可以解释许多引起众多争议讨论的奇特发现。
