Energy bunching in soft recollisions revealed with long-wavelength few-cycle pulses
Alexander Kästner, Ulf Saalmann, Jan M. Rost
Soft recollisions are laser-driven distant collisions of an electron with its parent ion. Such collisions may cause an energy bunching, since electrons with different initial drift…

Electron-energy bunching in laser-driven soft recollisions
Alexander Kästner, Ulf Saalmann, Jan M. Rost
We introduce soft recollisions in laser-matter interaction. They are characterized by the electron missing the ion upon recollision in contrast to the well-known head-on collisions…
