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 μm pulse pump.
