還是氘和氚的混合物。
Lawrence Livermore National Laboratory has its 1.8 MJ laser system running at full power. This laser system is designed to compress and heat a mixture of deuterium and tritium, which are both isotopes of hydrogen, in order to compress the isotopes to a fraction of their original size and fuse them into helium atoms (releasing neutrons in the process).[6]
