Ion Vortex Beam

Recent advances in intense short pulse laser interaction with thin foil enable us to accelerates the ions upto relativistic velocity in a controlled way. The accelerated ion beams can be utilized to generate the ion vortex beam in a similar way as it has been done for electron, neutron and photon vortex beam case. We present a theoretical demonstration of ion vortex beam with orbital angular mo- mentum (OAM) generated from a relativistic laser-matter interaction rearranged into vortex beam by using phase shifter or computer generated holography. We show that a Laguerre-Gaussian beam exit for Schrodinger, Klein-Gordon and Dirac particles. This study will motivate to explore the existence of ion vortex beam experimentally.
