摘　　要：激光惯性约束聚变(ICF)研究具有十分重要的实际价值和科学意义,同时也是依赖整体国力的大科学工程.内爆实验,集成理论、制靶、诊断和驱动器等多方面工作,是ICF研究水平的最终体现.我国从20世纪80年代实现激光驱动内爆出中子,到90年代至21世纪头十年实现以冲击压缩为主的近一维内爆,并且惯性压缩开始起作用,直至近期实现中等收缩比、方波驱动、以惯性压缩为主的近一维内爆,内爆实验水平不断进步,内能性能显著提升.随着神光-Ⅲ(SG-Ⅲ)装置的建成,同时在美国点火实验受挫的形势下,我国内爆实验向更高收缩比、更低燃料熵增的点火参数区间迈进,将面临重大机遇与挑战.Achieving ignition via inertial confinement approach is of strong application value and important science significance. It is also a project of large scale that depends on the national strength. Involving theory, target fabrication, diagnostics, and laser facilities, integrated implosion experiment plays an important role in the research of ICF. Since the first successful neutron production with directly driven implosion in the 80＇s, the quasi one-dimensional implosion performance dominated by shock compression was demonstrated in the period of 1990–2010, and the quasi one-dimensional implosion performance dominated by inertial compression was achieved in recent years. All of these facts definitely show the progress on improving the performance of integrated implosion. With the completion of SG-Ⅲ laser facility,and in the situation of facing frustration in the US ignition program, there is grand opportunity and challenge when we are exploring toward the ignition parameter space with higher convergence ratio and lower adiabat.
