NIF is the world’s most precise and reproducible laser system. It precisely guides, amplifies, reflects, and focuses 192 powerful laser beams into a target about the size of a pencil eraser in a few billionths of a second, delivering more than 2 million joules of ultraviolet energy and 500 trillion watts of peak power.

NIF targets are precisely controlled in a cryogenic cooling system that keeps the deuterium-tritium fuel frozen inside a millimeter-sized capsule. In a NIF ignition experiment, a tiny capsule containing two forms of hydrogen, deuterium (D) and tritium (T), is suspended inside a cylindrical x-ray “oven” called a hohlraum.

The National Ignition Facility (NIF) is a laser-based inertial confinement fusion (ICF) research device, located at Lawrence Livermore National Laboratory in Livermore, California, United States. NIF's mission is to achieve fusion ignition with high energy gain.

2025年2月24日 · NIF's increasing shot yields—including the achievement of fusion ignition—enable materials and components to be tested for nuclear survivability at hotter and more intense conditions. More News »

The National Ignition Facility (NIF) is an operational multi-megajoule laser facility at Lawrence Livermore National Laboratory (LLNL) in Livermore, CA. In March 2009, construction of NIF was completed and it began full operations.

The National Ignition Facility (NIF) is the world’s largest optical instrument, comprising 192 37 cm square beams, each generating up to 9.6 kJ of 351 nm laser light in a 20 ns beam precisely tailored in time and spectrum.

2017年3月23日 · The National Ignition Facility (NIF) laser is the culmination of more than 40 years of work at Lawrence Livermore National Laboratory dedicated to the delivery of laser systems capable of driving experiments for the study of high-energy-density physics.

On Dec. 5, a team at LLNL’s National Ignition Facility (NIF) conducted the first controlled fusion experiment in history to reach this milestone, also known as scientific energy breakeven, meaning it produced more energy from fusion than the laser energy used to drive it.

NIF’s injection laser system (ILS) plays a key role in meeting these three requirements. The ILS system is responsible for generating a prescribed temporal and spatial pulse shape, adjusting the energy in each of the 192 beams, and adjusting the time when the beams hit the target.

The National Ignition Facility (NIF) is the world's larg-est and most energetic 192-laser-beam system which con-ducts experiments in High Energy Density (HED) physics and Inertial Confinement Fusion (ICF). In December 2022, the NIF achieved a scientific breakthrough when, for the first time ever, the ICF ignition occurred under laboratory
