分析基于单芯光子晶体光纤的超连续谱光源在提升平均输出功率时所面临的问题,指出采用多芯光子晶体光纤作为超连续谱产生介质是一种实现高功率超连续谱产生的潜在方案。使用自制皮秒光纤激光器泵浦一段国产多芯光子晶体光纤,实现了光谱范围750～1700nm,平均功率42.3W的全光纤化高功率超连续谱输出。
The problem of superconducting spectrum light source based on single-core photonic crystal fiber in improving average output power is analyzed. It is pointed out that using multi-core photonic crystal fiber as supercontinuum generation medium is a potential solution for high-power supercontinuum generation. A self-made picosecond fiber laser was used to pump a domestic multi-core photonic crystal fiber to achieve all-fiber high-power supercontinuum output with a spectral range of 750-1700 nm and an average power of 42.3W.
