Supercontinuum generation

Supercontinuum generation is a combination of nonlinear optical effects that spectrally broaden an initially nearly monochromatic laser beam. This can be achieved, for example, by sending a short intense burst of light along a photonic-crystal optical fibre. Supercontinuum generation is used to provide intense sources of white light.
