Abstract
We propose a new ion acceleration scheme of irradiating a thin solid target with an ultraintense circularly polarized Laguerre-Gaussian laser pulse. Three-dimensional particle-in-cell simulations are performed to demonstrate that this scheme can generate a low- divergence high-density relativistic proton jet. By this scheme, the number of protons emitted with a small angle ($<1^\circ$) from the laser axis can be more than tens of times as high as that of the protons accelerated by a circularly polarized Gaussian pulse. The inward ponderomotive force of the Laguerre-Gaussian pulse drives such a proton beam along the laser axis.Keywords
