在本文中，我们将展示使用极端激光的光子-光子碰撞实验可以提供可测量的效应，提供关于QED本质的基本信息，它的拉格朗日量。分析了用两个反向传播的超强激光器进行光子散射实验的可能情况。我们讨论了脉冲宽度和宽度的重要性，波束重叠和信号检测的最佳方案，以及区分信号和噪声的方法。这将需要高精度的测量，并控制时间抖动和噪声。我们得出结论，这种实验在1023 W cm−2下几乎是可行的，而在1024 W cm−2下非常有希望。
In this paper we will show that photon–photon collision experiments using extreme lasers can provide measurable effects giving fundamental information about the essence of QED, its Lagrangian. A possible scenario with two counterpropagating ultra-intense lasers for an experiment to detect scattering between optical photons is analyzed. We discuss the importance of the pulse widths and waists, the best scenario for overlapping the beams and signal detection, as well as ways to distinguish the signal from the noise. This would need a high-precision measurement, with control of temporal jitter and noise. We conclude that such experiment is barely feasible at 10 23 W cm− 2 and very promising at 10 24 W cm− 2.
