The world's largest and highest-energy laser was certified to operate by the U.S. Department of Energy on March 27, 2009. In 2010, NIF will focus the intense energy of 192 giant laser beams on a BB-sized target filled with hydrogen fuel — fusing, or igniting, the hydrogen atoms' nuclei in the world's first controlled thermonuclear reaction. This is the same fusion energy process that makes stars shine and provides the life-giving energy of the sun.
