Supercontinuum generation from ultraviolet to mid-infrared [PDF]

, 2014
The advent of photonic crystal fibers (PCFs) has paved the road for commercial high-power supercontinuum light sources. The air-hole structuring in the PCF manipulates the properties of light and gives a tremendous degree of design freedom, which has ...
