    "abstract": "The generation of electron surface oscillations in overdense plasmas\nirradiated at normal incidence by an intense laser pulse is investigated.\nTwo-dimensional (2D) particle-in-cell simulations show a transition from a\nplanar, electrostatic oscillation at $2\\omega$, with $\\omega$ the laser\nfrequency, to a 2D electromagnetic oscillation at frequency $\\omega$ and\nwavevector $k\u003e\\omega/c$. A new electron parametric instability, involving the\ndecay of a 1D electrostatic oscillation into two surface waves, is introduced\nto explain the basic features of the 2D oscillations. This effect leads to the\nrippling of the plasma surface within a few laser cycles, and is likely to have\na strong impact on laser interaction with solid targets.",
