High power supercontinuum generation has witnessed rapid developments during the past few years. The mechanism and the latest achievements in high power supercontinuum generation are reviewed both for the continuous wave pump regime and the pulsed pump regime. The challenges in scaling the average power of supercontinuum generation are analyzed. Some of our works on high power supercontinuum generation are summarized, and perspectives for the future development are discussed.

A mid-infrared supercontinuum (SC) light source, which has important applications in many fields, has been extensively investigated in soft glass fibers. However, the poor instinct properties of soft glass fibers and the development of ultrashort pulse lasers left an opportunity for mid-infrared SC generation in silica fiber. Until now, silica fiber has been the commonly used medium for SC generation due to its outstanding properties. In this paper, mid-infrared SC generation in short silica photonic crystal fibers (PCFs) is investigated theoretically and systematically. In the case of a 1550�nm pump, the soliton self-frequency shift effect is utilized to extend the long wavelength edge of SC. Adopting a fiber that has a zero dispersion wavelength away from the pump pulse is a benefit for the suppression of blue spectral component and energy distribution in the long wavelength band. In the case of a 1950�nm pump, the generation of a red-shifted dispersive wave is an efficient way to extend the long wavelength edge of SC. Additionally, the coherence for femtosecond pulse pumping is discussed in this paper. Finally, the long wavelength edge of SC is beyond 3000�nm when a 1950�nm femtosecond pump pulse propagates in a PCF with negative dispersive slope around the pump pulse.

Supercontinuum has wide and important applications in a range of fields, so it is one of the hot research spots in recent years. In this paper the mechanism and the latest achievements in high power supercontinuum generation under continuous wave laser pump and pulsed laser pump regimes during the past several years are reviewed. The challenges and the problems that need to overcome in scaling the average output power of supercontinuum generation are analyzed. An all-fiber supercontinuum source constructed at the national university of defense technology is demonstrated with 177.6 W average output power which overcomes the problems of low splicing loss, facet damage of the output fiber, the heat treatment and the effective control of the nonlinear effects through the optimization of the whole system. To the best of the author's knowledge, the 177.6 W average output power is the highest value in ever reported ones.
