Design of Laser Fusion Reactordriven by Laser-Diode-Pumped Solid State Laser

This paper presents a conceptual design of a laser fusion reactor for direct irradiation implosion of a DT fuel pellet. The reactor is driven by a laser diode (LD)-pumped solid state laser. 4 MJ driver energy yields the maximum gain of 150. The driver will be operated at a repetition rate of 12 Hz. We propose the four module chamber-one laser system. Each module chamber is operated at 3Hz. A first wall is made of liquid-lithium-lead flows. The flows are guided by woven ceramic pipes, protecting the structural wall as well as breeding tritium. By adopting currently existing technologies, we designed a concept of a high efficiency- and high repetition rate-LD-pumped solid state laser driver.
