自从激光器诞生以来.它在原子和分子水平的激光-物质相互作用以及束缚电子的非线性光学研究中一直非常有效。在激光诞生的初期,它与电子伏和化学键的物理学有关。但在过去十年中,我们已看到产生高强度光的能力剧增,它较过去可能达到的水平高5、6个数量级。在这样的强度处,粒子、电子和质子通过与强激光场的相互作用,具有兆电子伏范围的动能。这为激光开辟了一个新时代——甚至与核物理结合的非线性相对论光学的时代。我们提出一条在未来十年中达到1026-1028W/cm2极高强度水平的途径,利用即将建成的兆焦耳激光装置,大大超过现在和不久将来的1023W/cm2强度范围。此种极高强度的激光器可将粒子加速至太电子伏和拍电子伏的高能前沿,有可能成为包括粒子物理、重力物理、非线性理论、超高压物理、天体物理和宇宙学在内的基本物理学的研究工具。
Since the birth of the laser, it has been very effective in laser-material interactions at the atomic and molecular levels as well as nonlinear optical studies that bind electrons. Early in the laser’s birth, it was related to the physics of electron-volt and chemical bonds. But over the past decade, we have seen a dramatic increase in the ability to generate high intensity light, which is five to six orders of magnitude greater than previously possible. At such intensities, particles, electrons and protons have kinetic energy in the megavolt range through interaction with strong laser fields. This opens up a new era for lasers - even the era of nonlinear relativistic optics that combines nuclear physics. We propose a way to achieve extremely high levels of 1026-1028 W / cm2 over the next decade, using the forthcoming MJ laser device to surpass the current and near future 1023 W / cm2 intensity range. Such extremely intense lasers accelerate particles to energetic frontiers that are too eV and electron-volt, potentially making them fundamental including particle physics, gravitational physics, nonlinear theory, ultra-high pressure physics, astrophysics, and cosmology Physics research tools.
