快速点火（FI）和冷却Yb：YAG陶瓷激光器的最新进展使我们能够设计一个1 MJ级的紧凑型IFE动力装置，其输出能量是以前中心点火方案的1/4。在FI方案的基础上，我们概念性地设计了一个由冷却Yb：YAG陶瓷激光器驱动的激光聚变发电站。新的激光器材料选择了冷却的Yb-YAG陶瓷。我们发现，用于点火的加热激光器可以与冷却的Yb：YAG陶瓷以及压缩激光器构造具有可接受的电-激光转换效率，包括用于冷却系统的电功率。提出了一种新的无烧蚀气体驻点的液壁反应器方案。
Recent progress on fast ignition (FI) and cooled Yb:YAG ceramic laser enable us to design an IFE power plant with a 1MJ-class, compact laser whose output energy is 1/4 of previous central ignition scheme. Basing on the FI scheme, we conceptually designed a laser fusion power plant driven with cooled-Yb:YAG, ceramic lasers. The cooled Yb-YAG ceramic was newly chosen as the laser material. We found that the heating laser for ignition could be constructed with the cooled Yb:YAG ceramics as well as the compression laser with acceptable electricity-laser conversion efficiencies including the electric power for the cooling system. A new reactor scheme for a liquid wall reactor that has no stagnation point of ablated gas was proposed.
