我们演示了连续波超连续谱产生扩展到可见光谱区域的泵浦光子晶体光纤在1.07微米与400 W的单模，连续波，镱光纤激光器。连续谱跨度超过1300 nm，平均功率高达50 W，光谱功率密度超过50 mW/nm。数值模拟和理解的物理机制，使我们确定的主要贡献的短波长扩展的高能量孤子的色散波的捕获和散射。
We demonstrate continuous wave supercontinuum generation extending to the visible spectral region by pumping photonic crystal fibers at 1.07 microm with a 400 W single mode, continuous wave, ytterbium fiber laser. The continuum spans over 1300 nm with average powers up to 50 W and spectral power densities over 50 mW/nm. Numerical modeling and understanding of the physical mechanisms has led us to identify the dominant contribution to the short wavelength extension to be trapping and scattering of dispersive waves by high energy solitons.
