1. Introduction . Inertial confinement fusion (ICF), as one of the most probable ways to realize controlled thermonuclear fusion, is expected to provide mankind with nearly unlimited clean energy [ 1 ]. The research work in the field of ICF is undoubtedly of great significance to the national economy, and military applications, as well as to the exploration of basic research. The laser driver, as a core ICF device, has attracted much attention and research since it was proposed [ 2 – 6...
