"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."
NIF was designed to produce extraordinarily high temperatures and pressures – tens of millions of degrees and pressures many billion times greater than Earth's atmosphere. These conditions currently exist only in the cores of stars and planets and in nuclear weapons. In a star, strong gravitational pressure sustains the fusion of hydrogen atoms. The light and warmth that we enjoy from the sun, a star 93 million miles away, are reminders of how well the fusion process works and the immense energy it creates.- more
