Rotational excitation and molecular alignment in intense laser fields
Rotational excitation and spatial alignment in moderate intensity radiation fields are studied numerically and analytically, using time-dependent quantum mechanics. Substantial rotational excitation is found under conditions typically used in time-resolved spectroscopy experiments. The broad rotational wave packet excited by the laser pulse is well defined in the conjugate angle space, peaking ...
متن کاملEnhanced recollisions for antisymmetric molecular orbitals in intense laser fields.
The peculiarities of antisymmetric molecular orbitals are investigated in very intense linearly polarized laser pulses. For this purpose, the ionization-recollision quantum dynamics is evaluated theoretically beyond the dipole approximation. As opposed to the usual situation, the laser magnetic field component is found to strongly enhance recollision probabilities for particularly oriented anti...
متن کاملZeeman effect induced by intense laser light.
We analyze spectral line shapes of hydrogenlike species subjected to fields of electromagnetic waves. It is shown that the magnetic component of an electromagnetic wave may significantly influence the spectra. In particular, the Zeeman effect induced by a visible or infrared light can be experimentally observed using present-day powerful lasers. In addition, the effect may be used for diagnosti...
متن کاملIntense Laser Sheds Light on Radiation Reaction
A ccelerated electrons emit electromagnetic radiation, an effect we can appreciate every day in the color of the sky or when antennas produce radio waves to send music to our cars. Perhaps a less familiar idea is that the emitted radiation exerts a backaction on the electron itself, which has a dampening effect like that of friction (Fig. 1). Physicists first studied this “radiation reaction” t...
متن کاملMany-body effects in molecular photoionization in intense laser fields; time-dependent Hartree-Fock simulations.
The time evolution of the reduced single electron density matrix for eight electrons in a one-dimensional finite box potential driven by an intense laser field is calculated by numerically integrating the time-dependent Hartree-Fock equations. We study the effects of the Coulomb interaction, field intensity, and frequency on the time profile of the ionization process. Our computed saturation io...
