at Aug.8,2021,the experiment at the National Ignition Facility(NIF)made a significant step toward ignition,achieving a yield of more than 1.3 megajoules(MJ).This advancement puts researchers at the threshold of fusion ignition,an important goal of NIF,and opens access to a new experimental regime.The record-setting experi-ment was the culmination of years of research and development in lasers,optics,diagnostics,target fabrication,exper-imental design,and computer modeling and simulation.In this article,we have investigated the development of fusion ignition in NIF,to provide the reference for Chinese laser fusion research.
