我们展示了具有全正常群速度色散的光子晶体光纤中超连续谱的产生。用紧凑型放大光纤激光器输出的压缩脉冲泵浦这种光纤的一小段，产生具有典型自相位调制特性的200 nm带宽连续谱。我们证明了超连续谱可以压缩到26fS的持续时间。因此，它在所有频率分量之间具有高度的相干性，并且是时间域中的单个脉冲。使用较长的一段光纤可以获得跨越800 nm的平滑、平坦的光谱。(C)2011年美国光学学会
We demonstrate supercontinuum generation in a photonic crystal fiber with all-normal group velocity dispersion. Pumping a short section of this fiber with compressed pulses from a compact amplified fiber laser generates a 200 nm bandwidth continuum with typical self-phase-modulation characteristics. We demonstrate that the supercontinuum is compressible to a duration of 26 fs. It therefore has a high degree of coherence between all the frequency components, and is a single pulse in the time domain. A smooth, flat spectrum spanning 800 nm is achieved using a longer piece of fiber. (C) 2011 Optical Society of America
