Molecules in intense laser fields : From Coulomb explosion to high order harmonic generation
The nonperturbative response of molecules in ultrashort (t < 20 femtoseconds), intense (I 10 W/cm ) laser fields can only be described by accurate numerical solutions of the corresponding time-dependent Schrödinger equation (non-relativistic) or Dirac (relativistic) equations. Different time scales, attosecond (10 s) for electrons, femtosecond (10 s) for nuclei make the accuracy of such numeric...
متن کاملMultiple high-order harmonic generation in the presence of intense laser and static magnetic fields
We perform a nonperturbative study of the effect of static magnetic fields on the multiple high-order harmonic generation (HHG) processes of atomic H in intense pulsed laser fields. The time-dependent Schrödinger equation in three spatial dimensions can be solved accurately and efficiently by means of the recently developed time-dependent generalized pseudospectral method (Tong X M and Chu S I ...
متن کاملHarmonic generation by atoms interacting with intense ultrashort laser pulses
The interaction of intense ultrashort laser pulses with a gas of argon atoms is numerically investigated. The investigation utilizes a model that solves both the time-dependent Schrödinger equation and the wave equation self-consistently. The time-dependent Schrödinger equation for single-active electron in the effective static potential and in the potential of electron-laser interaction is sol...
متن کاملDynamics of Atoms & Molecules in Intense Laser Fields
Intense laser fields, comparable in magnitude with the Coulomb field within atoms and molecules, can be generated by focussing high-energy and ultrashort laser pulses. When exposed to such a strongly perturbing field, molecules exhibit various exotic features that cannot be observed in weak laser fields. We are seeking a deeper understanding of the behavior of molecules in intense laser fields,...
متن کاملMultiple Ionization of Atoms in Intense Laser Fields
A new ultrahigh vacuum-compatible ( 10 11 mbar) "reaction microscope" was built to investigate multiple ionization of atoms and molecules in ultra-short (23 fs), intense laser pulses (1014 1016 W/cm2, 795 nm) . In first experiments ion momentum distributions for single and double ionization of noble gas atoms in the nonsequential and sequential intensity regime were measured using linearly pola...
