我们首次演示了有效的倍频程跨越孤子的自频移。为了实现这一点，我们使用了一种光子晶体光纤，它具有较低的OH吸收和较大间隔的零色散波长。据我们所知，这是报道的基于光纤的可调谐信号源的最大频率跨度。此外，我们还观察到当红移在反常色散区边缘饱和时，钛宝石激光器以切伦科夫发射的形式直接产生2μm以上的光。
We report the first demonstration of efficient, octave spanning soliton self-frequency shift. In order to achieve this we used a photonic crystal fiber with reduced OH absorption and widely spaced zero-dispersion wavelengths. To our knowledge, this is the largest reported frequency span for a tunable, fiber-based source. In addition, we observe the generation of light above 2 μm directly from a Ti:Sapphire laser in the form of Cerenkov emission by the soliton when the red-shift saturates at the edge of the anomalous dispersion region.
