High-power solid-state laser technology development has been conducted so far for more than thirty years for application to inertial confinement fusion. Over twenty laser facilities have been built with the output energy of about a hundred Joules at the beginning up to severa tens of thousands Joules later in USA, Japan, France, China, Bratain, Russia and so on. In recent years, a few powers have been working very hard to build huge facilities, such as the NIF in USA, the LMJ in France, the SG—Ⅲ in China and the Iskra-6 in Russia. Numerous advanced technologies have to be developed to support the construction of the facilities. However, the most challenging task is to study, from the point of view of engineering science, how to build such huge facilities featured with high cost, high technical risk, and a long time period, in a cost-effective manner.
