In December 2022, the National Ignition Facility (NIF) of the Lawrence Livermore National Laboratory (LLNL), USA, reported the first demonstration of fusion ignition—the production of more energy from fusion than the laser energy used to drive the reaction. That result stemmed in no small part from remarkable advances in optical technology since ground was first broken on NIF in the mid-1990s. To learn more, OPN talked with Tayyab Suratwala, NIF’s program director for Optics and Materials Science and Technology.
