论文摘要
相对论强度的激光 - 血压相互作用触发的范式转移现象之一是所谓的相对论透明度。当电子被激光加热到相对论能量时，即使血浆密度足够高以反映非偏见的情况下的激光脉冲，血浆也会与激光透明。本文强调了相对论透明度可以通过关注与相对论透明度的开始相关的集体现象来对激光 - 物质相互作用产生的影响：热向向性各向异性相对论的等离子体中的等离子体双发性。这种系统的光学特性取决于光的极化，这可以作为基于等离子体的光学设备或新型诊断能力的基础。
One of the paradigm-shifting phenomena triggered in laser-plasma interactions at relativistic intensities is the so-called relativistic transparency. As the electrons become heated by the laser to relativistic energies, the plasma becomes transparent to the laser light even though the plasma density is sufficiently high to reflect the laser pulse in the non-relativistic case. This paper highlights the impact that relativistic transparency can have on laser-matter interactions by focusing on a collective phenomenon that is associated with the onset of relativistic transparency: plasma birefringence in thermally anisotropic relativistic plasmas. The optical properties of such a system become dependent on the polarization of light, and this can serve as the basis for plasma-based optical devices or novel diagnostic capabilities.
