摘　　要：随着特种光纤制造工艺与高亮度激光二极管抽运技术的发展,超连续谱输出平均功率得到快速提升,目前已超过百瓦。在简要介绍国内外高功率超连续谱光源研究概况的基础上,分析了高功率超连续谱光源的关键技术,介绍了国防科学技术大学近几年在高功率超连续谱光源方面所做的相关工作:利用脉冲光纤激光器抽运国产光子晶体光纤取得平均功率为101W的超连续谱输出;采用大模面积双包层光纤放大器直接输出超连续谱方案,得到177W近红外超连续谱输出;利用2μm脉冲光抽运ZBLAN光纤,获得10W中红外超连续谱输出。With the development of special fiber fabrication technology and the pumping technology with high brightness laser diode, the average output power of supercontinuum source increases dramatically to hundred watt level in recent years. Based on the introduction of recent developments in high power supercontinuum fiber source, the key technologies of high power supercontinuum generation are analyzed. The up-to-date progress on high power supercontinuum fiber source in the National University of Defense Technology is presented： 101 W supercontinuum average output power is extracted from a homemade photonic crystal fiber by using a pulsed fiber laser as the pump, 177 W near-infrared supercontinuum power is obtained directly from a large-mode-area double-cladding fiber amplifier~ 10 W mid-infrared supercontinuum is achieved from a ZBLAN fiber with a 2 ~m pulse pump.
