摘要
采用平均功率为141.6 W的皮秒光纤激光泵浦一段国产七芯光子晶体光纤,获得了平均功率为104.2 W、连续光谱覆盖范围从750至1700 nm以上的超连续谱输出.详细研究了超连续光谱随泵浦功率增加的演变过程,并对基于该七芯光子晶体光纤的超连续谱光源的光谱拓展和功率提升潜力进行相关的分析和讨论.该研究结果对高功率超连续谱光源的发展具有一定的参考价值.
A 104.2 W supercontinuum spanning from 750 nm to beyond 1700 nm is generated by pumping a piece of home- made seven-core photonic crystal fiber with a 141.6 W picosecond fiber laser. The evolution of the output spectrum is investigated in detail with the increase of the picosecond laser power. The feasibilities of broadening the spectral range and scaling the output power for the supercontinuum source based on the seven-core photonic crystal fiber are analyzed and discussed. The research results will make a contribution to the further development of high-power supercontinuum source.
