超连续谱的产生是光子晶体光纤的重要应用之一。将脉宽小于1 ns、重复频率约为6.85 kHz、平均输出功率小于100 mW、中心波长约为1064.5 nm的脉冲激光注入一段长度约为15 m，结构参数为：空气孔直径d=2.205 μm,孔间距Λ=3.359 μm，纤芯直径约为4.5 μm，零色散波长λZDW=1016 nm的高非线性光子晶体光纤中，获得了频谱宽度超过1100 nm的超连续谱。该超连续谱也为脉冲激光，其重复频率与抽运脉冲激光相同，单个脉冲宽度由于色散作用有所展宽。除残余抽运光在1064.5 nm处产生一个高峰，在测量频带600~1700 nm内超连续谱的光谱强度非常平坦，变化在10 dB以内，是一个较好的超连续谱白光光源。

Supercontinuum generation is one of the most important applications of photonic crystal fibers. An optical pulsed laser, of pulse width smaller than 1 ns, repetition rate about 6.85 kHz, average output optical power lower than 100 mW, and central wavelength near 1064.5 nm, is used to pump a segment of highly nonlinear photonic crystal fibers with length about 15 m, air hole diameter 2.205 μm, hole-hole space 3.359 μm, average core diameter 4.5 μm, zero dispersion wavelength 1016 nm. Then a flat supercontinuum of spectrum span over 1100 nm is obtained. The supercontinuum is also a series of optical pulses, whose repetition rate is the same as the pumping pulse, and each single pulse is broaden due to the dispersive effect. Except the peak at 1064.5 nm, which is generated by the residual pumping optical power, the power fluctuation is within 10 dB over the whole measuring range of 600~1700 nm. Therefore, an excellent supercontinuum, of low optical power and flat spectrum response, is obtained. It is very useful in various optical measurements, such as ultra-broadband super-width dispersion measurement of fibers.
