Abstract
We show the first coherent white-light optical vortices generated from supercontinuum that have the azimuthally varying phase structure consistent with a monochromatic Laguerre-Gaussian beam and zero angular dispersion. Two methods of Laguerre-Gaussian supercontinuum generation are discussed and contrasted. We use a computer generated hologram to convert a Gaussian white-light supercontinuum source into Laguerre-Gaussian supercontinuum.
