高能量密度物理(HEDP)是研究能量密度超过1011 J/m3的极端条件下物质结构与特性及变化规律的科学,开展此方面的研究对惯性约束聚变、材料物理、天体物理、加速器物理、**等具有极其重要的意义。主要介绍了我们在利用飞秒相对论性超强激光进行高能量密度物理研究方面所取得的一些进展,包括电子加速、离子加速(包括质子和重离子)以及其他一些有意义的结果。

In the field of high energy density physics (HEDP),the structures,characteristics and evolutions of the matter with the energy density of 1011 J/m3 are researched. HEDP plays an important role in inertial confinement fusion,material physics,astrophysics,accelerator physics and national defense. Some developments on HEDP by using femtosecond relativistic laser have been shown,including electron acceleration,ion acceleration (proton and heavy ions) and others interesting results.
