The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in California is the world's largest and most energetic laser system. The facility completed construction in 2009 and is designed to achieve fusion "ignition"-the achievement of a self-sustaining, burning plasma that releases a net amount of energy. If achieved, it would mark the culmination of more than 50 years of research into fusion. In 2012, the NIF laser met and exceeded its design criteria for energy and power, but it has not yet attained the goal of ignition of the fusion fuel.
