| 1 | ARCTURUS laser: a versatile high-contrast,high-power multi-beam laser system显示文摘With the latest configuration,the Ti:Sa laser system ARCTURUS(Düsseldorf University,Germany)operates with a double-chirped pulse amplification(CPA)architecture delivering pulses with an energy of 7 J before compression in each of the two high-power beams.By the implementation of a plasma mirror system,the intrinsic laser contrast is enhanced up to 10^-12 on a time scale of hundreds of picoseconds,before the main peak.The laser system has been used in various configurations for advanced experiments and different studies have been carried out employing the high-power laser beams as a single,high-intensity interaction beam(I≈1020 W/cm^2),in dual-and multi-beam configurations or in a pump–probe arrangement. | M.Cerchez R.Prasad B.Aurand A.L.Giesecke S.Spickermann S.Brauckmann E.Aktan M.Swantusch M.Toncian T.Toncian O.Willi | 2019 | High Power Laser Science and Engineering2019，7，3： | 1 |
| 2 | Relativistic electron acceleration by surface plasma waves excited with high intensity laser pulses显示文摘The process of high energy electron acceleration along the surface of grating targets(GTs)that were irradiated by a relativistic,high-contrast laser pulse at an intensity I=2.5×10^20 W/cm^2 was studied.Our experimental results demonstrate that for a GT with a periodicity twice the laser wavelength,the surface electron flux is more intense for a laser incidence angle that is larger compared to the resonance angle predicted by the linear model.An electron beam with a peak charge of∼2.7 nC/sr,for electrons with energies>1.5 MeV,was measured.Numerical simulations carried out with parameters similar to the experimental conditions also show an enhanced electron flux at higher incidence angles depending on the preplasma scale length.A theoretical model that includes ponderomotive effects with more realistic initial preplasma conditions suggests that the laser-driven intensity and preformed plasma scale length are important for the acceleration process.The predictions closely match the experimental and computational results. | X.M.Zhu R.Prasad M.Swantusch B.Aur A.A.Andreev O.Willi M.Cerchez | 2020 | High Power Laser Science and Engineering2020，8，2： | 0 |
