Researchers at the Osaka University in Japan produced LFEx, which stands for "laser for fast ignition experiments." This is the world's most powerful laser ever made, able to produce a 2,000-trillion watt laser beam. It fires in very short bursts, lasting about one trillionth of a second. This laser can vaporize matter and generate plasma.
