Abstract
The generation of non-diffracting light fields using broadband and incoherent light sources have made important impact in physics. The white Bessel light modes are made from laser diodes operating below threshold, supercontinuum light sources and halogen bulbs. The superposition of the conical wave-vectors arising from passage through the axicon and the inherent absence of chromatic aberration results in a pure focal line of white light. White light sources are used in a wide variety of applications, including imaging using optical coherence tomography. It is believed that exploiting the coherence properties of light in combination with sculpting the wavefronts will lead to new innovations.
