摘要
利用1064 nm抽运光在总长度为1 m的光子晶体光纤(PCF)的前半段（77 cm）通过四波混频产生747 nm短波信号光，并对光纤的后半段进行拉锥处理，拉锥光纤具有707 nm和1177 nm两个零色散点(ZDW)。利用1064 nm抽运光和产生的747 nm信号光共同在两个零色散点之间的反常色散区抽运拉锥光子晶体光纤，在长度大约27 cm的拉锥光子晶体光纤中产生了谱宽大于600~1700 nm（带宽20 dB以内）的超连续谱输出。
Abstract
By using 1064 nm pulsed laser the front section (77 cm) of photonic crystal fiber (PCF) is pumped and 747 nm signal light is got by four-wave mixing. The end part of the PCF is tapered and has two zero-dispersion wavelengths (ZDW). The 747 nm signal light and 1064 nm pulsed laser which locate in the anomalous dispersion regime between two zero-dispersion wavelengths are pumped into the tapered PCF. Supercontinuum with more than spectral width of 600~1700 nm (at 20 dB level) is generated in the tapered PCF which has 25 μm outer diameter and 27 cm length.
