    "abstract": "A thin and dense plasma layer is created when a sufficiently strong laser\npulse impinges on a solid target. The nonlinearity introduced by the\ntime-dependent electron density leads to the generation of harmonics. The pulse\nduration of the harmonic radiation is related to the risetime of the electron\ndensity and thus can be affected by the shape of the incident pulse and its\npeak field strength. Results are presented from numerical\nparticle-in-cell-simulations of an intense laser pulse interacting with a thin\nfoil target. An analytical model which shows how the harmonics are created is\nintroduced. The proposed scheme might be a promising way towards the generation\nof attosecond pulses.\n  PACS number(s): 52.40.Nk, 52.50.Jm, 52.65.Rr",
