中文摘要：
报道了一种双包层七芯光子晶体光纤，其零色散点在1036nm，在波长1060nm处非线性系数为2．43W^-1．km^-1采用中心波长为1060nm、脉冲宽度为160ps、重复频率为1MHz、光束质量M^2〈1．3、最大输出率为4．5W的增益开关皮秒脉冲全保偏光纤激光器抽运35m的七芯光子晶体光纤，得到最大输出功率为2．443W、谱宽范围500～1700nm的全光纤化超连续谱输出。实验所测的超连续谱输出远场与模拟的同相位超模远场分布非常吻合，故对高功率超连续谱产生具有参考价值。
英文摘要：
A double cladding seven-core photonic crystal fiber （PCF） is reported with zero dispersion wavelength （ZDW） at 1036 nm and the nonlinear coefficient of 2.43 W-1 ·km^-1 at 1060 nm. A gain-switched all polarization- maintaining fiber laser system with central wavelength of 1060 nm, pulse width of 160 ps, repetition rate of 1 MHz, beam quality M^2〈1.3 and average power of 4.5 W is utilized to pump a 35 m-long seven-core PCF, allowing the supercontinuum generation （SCG） with output power of 2. 443 W covering wavelength from 500 nm to 1700 nm. The far field of seven-core PCF is measured, the pattern of which is in agreement with the calculated far field of in-phase supermode. The experiment can be a useful reference for the high power supercontinuum source.
