Laser fusion

摘要

The US National Ignition Facility (NIF) revealed last week that its 192 lasers had combined to fire a shot with an energy of 1.875 megajoules - a milestone in efforts to trigger fusion by imploding a frozen fuel pellet of hydrogen isotopes. The energy means that the facility, at the Lawrence Livermore National Laboratory in Livermore, California, has surpassed its design specifications.
