Abstract :
We study numerically and experimentally the process of cascaded four-wave mixing of a vortex beam imposed on short laser pulses propagating in a gas cell. We demonstrate that such cascaded nonlinear process leads to the generation of white-light optical vortices with well preserved vortex phase profile.
