In this work, we perform a computational investigation of direct acceleration of electrons produced during ionization of underdense neon gas using a tightly focused and radially polarized Petawatt-class short pulse lasers by numerically solving the relativistically invariant Lorentz equations, incorporating semi-classical tunneling ionization and Monte Carlo type sampling of the focal volume.
