Investigation of hundred-watt-level supercontinuum generation in photonic crystal fiber*
-
摘要: 采用脉冲重复频率可调的高功率皮秒脉冲光纤激光抽运光子晶体光纤产生了平均输出功率为101 W 的全光纤化超连续谱。通过一系列的对比实验，详细研究了抽运激光的脉冲重复频率以及光子晶体光纤的长度对超连续谱产生的影响。最后，对如何实现更高平均功率的超连续谱输出进行相关的分析和讨论。相关研究结果可以为进一步发展基于光子晶体光纤的高功率超连续谱光源提供一定的参考。Abstract: A 101 W all-fiber supercontinuum soure is demonstrated by seeding a piece of photonic crystal fiber with a high-power pulse-repetition-rate-tuning picosecond fiber laser. By performing a series of comparative experiments, influences of the pump pulse repe-tition rate and the photonic crystal fiber length on the supercontinuum generation process are investigated in detail. How to improve the power level of the supercontinuum soure is analyzed and discussed. The research results will make a contribution to the further development of high-power supercontinuum soure.
