America Fires the Most Powerful Laser In History
The United States' National Ignition Facility at the Lawrence Livermore National Lab in California has fired the most powerful laser in history, a record-breaking 2-megajoule shot. The laser was originally designed to reach 1.875-megajoules, but beat everyone's expectations—and set a new world record in the process.
192 laser beams combined to form the single shot, initially reaching 1.875 megajoules. By the time it passed through its final focusing lens, the laser maxed out at 2.03 megajoules, making it the world's first 2-megajoule ultraviolet laser. Better yet, the blast caused less damage to the laser optics than predicted, which allowed the facility to fire another shot just 36 hours after the 2.03-megajoule one.
How it works
It all starts with a single laser, which is split into 48 separate beams. The beams
