激光技术的最新进展使我们能够在实验室中研究空间和天体物理现象。在空间等离子体中，航天器的局部观测为我们提供了等离子体和电场/磁场的微观信息，但很难获得这些现象的整体结构。相比之下，在天体物理等离子体中，全球图像为我们提供了宏观信息，尽管没有局部观测，因此也没有微观信息。空间和天体物理现象的实验室实验同时为我们提供了局部和全球的信息。到目前为止，我们主要研究了具有长激光脉冲的宇宙中的非相对论现象。现在，我们用超强激光将我们的研究从非相对论扩展到相对论状态，这是国立中央大学的100TW激光设备。我们介绍了我们的设备和实验室中的相对论现象模型，重点是磁场的产生和宇宙中的磁重联。(C)2014爱思唯尔B.V.保留所有权利。
Recent progresses of laser technologies enable us to investigate space and astrophysical phenomena in laboratories. In space plasmas the local observations by spacecrafts provide us the microscopic information of the plasma and electric/magnetic fields, however, it is difficult to obtain the global structures of the phenomena. In astrophysical plasmas, in contrast, global images provide us the macroscopic information, although there is no local observation and thus no microscopic information. Laboratory experiments on space and astrophysical phenomena provide us the local and global information simultaneously. We have investigated so far mostly non-relativistic phenomena in the universe with long laser pulses. Now we extend our research from non-relativistic to relativistic regime with an ultra intense laser, the 100 TW laser facility at National Central University. We introduce our facility and model relativistic phenomena in laboratory, focusing on the magnetic field generation and the magnetic reconnection in the universe. (C) 2014 Elsevier B.V.
