与强激光场相互作用的原子可以发射出能量非常高的电子和光子。这些高度非线性过程的直观和定量解释可以在经典牛顿粒子轨道的推广方面找到，即所谓的量子轨道。要重现实验结果，只需要很少的量子轨道。这些轨道被清楚地识别，从而为有效的控制以及这些过程的先前未知的应用开辟了道路。
Atoms interacting with intense laser fields can emit electrons and photons of very high energies. An intuitive and quantitative explanation of these highly nonlinear processes can be found in terms of a generalization of classical Newtonian particle trajectories, the so-called quantum orbits. Very few quantum orbits are necessary to reproduce the experimental results. These orbits are clearly identified, thus opening the way for an efficient control as well as previously unknown applications of these processes.
