激光-物质相互作用领域传统上处理原子、分子和等离子体对外部光波的响应。然而，最近持续的技术进步正在开辟利用强激光辐射来触发或实质性地影响原子物理学能量尺度以外的物理过程的可能性。可用的光学激光强度超过10（22）W/cm（2）可以将基本的光-电子相互作用推到极端极限，其中辐射反应效应主导电子动力学，可以揭示量子真空的结构，并且可以触发粒子的产生，例如电子，μ子和π子及其相应的反粒子。此外，强相干高能光子的新来源和基于激光的粒子对撞机可以为核量子光学铺平道路，甚至可能允许发现超越标准模型的新粒子。这些是这篇文章的主要议题，这是专门审查最近的调查范围内的相对论量子动力学，量子电动力学，核和粒子物理学的高能过程，发生在极强的激光场。
The field of laser-matter interaction traditionally deals with the response of atoms, molecules, and plasmas to an external light wave. However, the recent sustained technological progress is opening up the possibility of employing intense laser radiation to trigger or substantially influence physical processes beyond atomic-physics energy scales. Available optical laser intensities exceeding 10(22) W/cm(2) can push the fundamental light-electron interaction to the extreme limit where radiation-reaction effects dominate the electron dynamics, can shed light on the structure of the quantum vacuum, and can trigger the creation of particles such as electrons, muons, and pions and their corresponding antiparticles. Also, novel sources of intense coherent high-energy photons and laser-based particle colliders can pave the way to nuclear quantum optics and may even allow for the potential discovery of new particles beyond the standard model. These are the main topics of this article, which is devoted to a review of recent investigations on high-energy processes within the realm of relativistic quantum dynamics, quantum electrodynamics, and nuclear and particle physics, occurring in extremely intense laser fields.
