摘要: We demonstrate two-color dispersive wave emission in the ultraviolet and near-infrared regions an argon filled hypocycloid-core kagome fiber pumped by a femtosecond laser around 1 μm. These two waves show drastically distinct features terms of bandwidth tunability. The region has tens nanometers can be widely tuned from at least 267 nm to 460 changing gas pressure, input pulse energy, pump wavelength. In contrast, narrower ~5 is quite stably positioned near edge fundamental transmission band even if pressure or energy significantly changed. An antiresonant tube model applied explain experimental results good agreement found between them. dynamics that narrow-band originates steep slope dispersion band.
