In a major breakthrough for nuclear fusion research, scientists at the National Ignition Facility (NIF) in California have achieved a record-breaking energy output from a fusion reaction, exceeding 2.1 megajoules of energy. This is the first time that a fusion experiment has produced more energy than the amount of laser energy that was delivered to the fuel.
Nuclear fusion is the process of fusing light atomic nuclei, such as hydrogen, into heavier ones, such as helium, releasing enormous amounts of energy in the process. This is the same process that powers the sun and other stars. However, achieving and sustaining fusion on Earth is extremely challenging, as it requires extremely high temperatures and pressures to overcome the natural repulsion between the nuclei.

The NIF is the world’s largest and most energetic laser facility, capable of delivering over 2 megajoules of ultraviolet laser light to a tiny target containing a mixture of deuterium and tritium, two isotopes of hydrogen. The laser pulses create a shock wave that compresses and heats the fuel to the point of ignition, triggering a fusion reaction that releases more energy than the laser input.
The NIF team has been working towards this goal for over a decade, overcoming various technical and scientific hurdles along the way. The latest experiment, conducted on November 8, 2023, marks a significant milestone for the field of nuclear fusion, as it demonstrates the feasibility of achieving net energy gain from fusion, a key requirement for developing fusion reactors that can produce clean and limitless energy for the world.
“This is a remarkable achievement that shows that we are on the right track towards our ultimate goal of achieving ignition and self-sustaining fusion,” said Dr. Kim Budil, the director of Lawrence Livermore National Laboratory, which operates the NIF. “We are very proud of our team and our partners who have made this possible, and we are grateful for the support of the Department of Energy and the National Nuclear Security Administration.”
The NIF team plans to continue their experiments to optimize the fusion performance and explore the physics of ignition and burn. They also hope to collaborate with other fusion research facilities around the world, such as the International Thermonuclear Experimental Reactor (ITER) in France, to advance the science and technology of fusion energy.
