The L3-HAPLS advanced petawatt laser system was installed last week at the ELI Beamlines Research Center in Dolní Břežany, Czech Republic. L3-HAPLS – the world’s most advanced and highest average power, diode-pumped petawatt laser system—was designed, developed and constructed in only three years by Lawrence Livermore National Laboratory’s (LLNL) NIF and Photon Science (NIF&PS) Directorate and delivered to ELI Beamlines in June 2017.
