采用当前最先进的激光装置与物质相互作用，可以获得与天体物理过程中相同或相似的条件，并进而开展利用激光等离子体模拟天体物理现象的实验.然而，激光等离子体为微米空间尺度、纳秒存活时间，而天体物理对象则为宇宙学的极大的时间与空间尺度，对在物理上和实际操作上将这两种表面上存在巨大差异的物理过程对应起来从而利用激光等离子体研究天体物理过程的可能性进行了讨论，特别是对利用国内的激光装置开展模拟实验的可行性进行了讨论.

The use of the state-of-the-art laser facility makes it possible to create conditions of the same or similar to those in the astrophysical processes.The introduction of the astrophysics-relevant ideas in laser-plasma experiments is propitio us to the understanding of the astrophysical phenomena.However,the great difference between the laser-produced plasmas and the astrophysical processes makes it awkward to model the latter by laser-plasma experiments.This paper addresses the physical backgrounds for modeling the astrophysical plasmas by laser plasmas, connecting these two kinds of plasmas by scaling laws.Thus,allowing the creation of experimental test beds where observations and models can be quantitatively compared with laser-plasma data.Special attentions are paid on the possibilities of using home-made laser facilities to model astrophysical phenomena.
