Generation of white-light optical vortices through cascaded four-wave mixing

Hansinger, P; Maleshkov, Georgi; Garanovich, Ivan; Skryabin, D; Neshev, Dragomir; Dreischuh, Alexander; Paulus, GG; Kivshar, Yuri


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.
