White light 50 W supercontinuum: roadmap to kW truly white lasers

In this paper we demonstrate a 51.5 W supercontinuum spanning 405 nm to 2660 nm with endlessly single mode output, and a blue enhanced 33.6 W supercontinuum spanning 380 nm to 2575 nm. We also show results combining 7 SC laser outputs, resulting in 26 W visible power. This method of combining fiber laser outputs can be scaled up, creating a pathway to kW level supercontinuum fiber lasers with greater than 95 W in the visible part of the spectrum.
