高能量密度物理(HEDP)是一个近年发展起来的充满新物理现象和具有重要应用前景的交叉前沿领域。高能量密度状态在天体中普遍存在。随着高功率激光器、高能粒子束和Z-箍缩发生器的发展,在实验室产生高能量密度的条件日益成熟。对基于强激光的高能量密度物理的研究现状和几个前沿问题进行了简单介绍,重点综述激光惯性约束聚变快点火方案和实验室天体物理的新进展。

High energy density physics(HEDP) is a rapidly growing frontier field,in which new physical phenomena are rich and important applications have been applied or prospected. The matter of high energy density is normal in universe. However,with the developments of high-power laser,Z-pinch,and ion accelerator facility,it is feasible to create such matter in laboratories. New developments and important scientific problems of high-power laser-based HEDP particularly on the fast ignition of inertial confinement fusion and laboratory astrophysics are briefly introduced.
