最先进的快速点火方案之一是快速点火实现实验。第一阶段的目标是演示5 keV的点火温度，然后是第二阶段演示点火和燃烧。2010年底至2011年初，FIREX-I的第二系列实验表明，从激光到压缩核心的热能的耦合效率很高（>10%），这表明可以在低于10 kJ的激光能量下实现点火温度。通过引入激光驱动磁场，有望进一步提高耦合效率。
One of the most advanced fast ignition programmes is the fast ignition realization experiment (FIREX). The goal of its first phase is to demonstrate ignition temperature of 5 keV, followed by the second phase to demonstrate ignition-and-burn. The second series experiment of FIREX-I, from late 2010 to early 2011, has demonstrated a high (>10%) coupling efficiency from laser to thermal energy of the compressed core, suggesting that the ignition temperature can be achieved at laser energy below 10 kJ. Further improvement of the coupling efficiency is expected by introducing laser-driven magnetic fields.
