Absztrakt:
Strong and short laser pulses provide new experimental techniques to study
electronic motion on atomic scales. In above threshold ionization of atoms,
the energy gain of photoelectrons is increased by electron-ion collisions.
Heating of plasmas by inverse bremsstrahlung absorption is based on electron-
ion collisions correlated by the laser field. In this talk we will review and
extend theories and computations on electron-ion collisions and above
threshold
ionization in strong laser fields. Starting from classical instantaneous
collisions, we illustrate time-dependent behaviour by a classical binary
collision model. The quantum-mechanical behaviour is then studied in terms of
numerical solutions of the time-dependent Schrödinger equation and by
analyzing the evolution of the corresponding Wigner quasi-probability in phase
space.
