报道了利用20 fs激光脉冲在两种多孔微结构光纤产生超连续谱的现象，光纤长度均为40 cm，连续谱展宽范围分别是420—980 nm 和570—920 nm 。实验上证明了不仅仅具有周期性结构的微结构光纤可以用于产生超连续谱，由无序填充气孔组成的多孔微结构光纤也可以出现类似的超强非线性和超连续谱展宽。分析表明，小模场面积和高非线性系数更有利于产生宽的超连续谱，完全光子带隙的存在导致了光谱的分立结。-reported the use of 20 fs laser pulses in both micro-porous structure Fiber-continuous spectrum of phenomena, Fiber length was 40 cm, Continuous spectrum broadening the range of 420-980 nm and 570-920 nm. Experiment has proved not only a cyclical structure of the micro-fiber can be used to produce ultra-continuous spectrum, from disorderly filled porosity of porous microstructure fiber can be similar to the super-nonlinear and continuous spectrum width. Analysis shows that small-scale market area and the high nonlinear coefficient is more conducive to have a wide-continuous spectrum, completely PBG lead to the existence of the separation of the spectra Guitar.
