In the famous three-step model the driving light field ionizes the electron by tunnel ionization, accelerates it away and back to the ionic core, where the electron re-collides and emits XUV light if it recombines.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\ud83d\ude17 The motion of an electron in a strong infrared laser field is tracked in real time by means of a novel method developed by MPIK physicists and applied to confirm quantum-dynamics theory by cooperating researchers at MPI-PKS.
