Abstract: By using three-dimensional particle-in-cell simulations, we demonstrate that an energetic ring-shaped ion beam can be generated by an ultra-intense circularly polarized Laguerre–Gaussian laser pulse interacting with micro-structure targets. The electron and ion dynamics of three… read more here.

DOI: 10.1070/qel16301
Abstract: The interaction of a thin plasma foil with two counterpropagating circularly polarised Laguerre – Gaussian laser beams of ultra-high intensity is studied using pwarticle-in-cell simulations in a fully three-dimensional geometry. It is found that within… read more here.

DOI: 10.1364/oe.470128
Abstract: For the specific energy distribution of Gaussian laser, the obtained grooves always fall short in the sidewall verticality. To overcome this problem, the improvement of sidewall inclination in laser grooving of a CVD diamond is… read more here.
